I have a database that records all procurements and requisitions of our medical supplies.
I have set up queries that sum all requisitions in a set time frame for each item that should be in the store (i.e. this month, this year etc) and similar query for the procurements.
A further query then subtracts the requisitions from the procurements and (should) give me an inventory of all medical supplies.
BUT.....
If no items have been procured or requisitioned, they are excluded from the sums. We have a standard list of items (which is a table in the DBase) and I need to know if we have no stock (there are certain things we can't get all the time in Tanzania, so procurements and requisitions are zero/nul for a while and I need the Dbase to highlight the lack of items).
Please help!
Note, if there is away of doing this with out VB I would be very happy as I have never used VB and it terrifies me.
Hi Everyone! Bear with me, I'm new to Access and I may not understand or use all the terminology correctly.
Background: I'm creating a database to track the inspections of many businesses. Each business will have many inspections throughout the year and each inspection has many items. I have a form set up which includes Business info and Inspection info (#items inspected, subtotal for inspection) on the main form, and Items in error listed on a subform (no error=no items listed).
Problem 1: I need to make a count of all items that are listed. I can do this in the subform, with no problem (in one of the footers #Discrep:count([item])) but now I need to report and use that value on the main form to calculate the percent error for the entire inspection. I don't know how to pull in onto the main form to set up my calculation. :confused:
Problem 2: This one is related and is probably the same fix. I have PriceCharged and PostedPrice for each item. I need to calculate the net error and then, using the subtotal on the main form, calculate the % dollar error.
Any suggestions, oh great and powerful gurus of the Access world? I hope I explained that clearly enough for you. Thank you very much in advance! ~Lith
I have a query that I run to extract some values for calculations. Its run on an event based on a dropdown selection. At the moment, I run via:
Code: DoCmd.OpenQuery "CallMidprice"
and then close it. this seems to take more time than is necessary when I only want to refresh the results.Open query without close, switches to the table but doesn't update until I press F5.When I try requery I get an error. "Runtime error '2109': There is no field named 'CallMidprice' in the current record.
Requery without 'Callprice' seems to requery my form.
I have a database where I need to record student data, specifically marks and absenteeism. The marks are recorded each term as a running total. I have a final mark which needs to be equal to the 4th term mark.
I also need to record the number of days absent each term with a total at the end of the year.
My problem is that the term 4 mark is a in the previous record and the total days absent needs to be the total of the previous 4 records (term 1 - 4).
I using a create table query and an update query but that was a no go.
My boss wants me to program in visual basic, instead of using queries, a calculation between times, which values are gotten from a table. How do I perform a calculation between two fields from a table in code and what functions are there to calculate the amount of difference in minutes between times in visual basic? THANK YOU SO MUCH IN ADVANCE!
I have solved the problems getting values on the subform. I have not in getting values on the subform.For instance, on the one titled phone use the formula in the tutorial is:
=[sbfCustomerRoomUse].[Form]![txtTotalPhoneUse]
#Error results when the doc is put into a form mode.
Now when I input each value in the equation above separately.I still get no entry.
For " = sbfCustomerRoomUse" , I get #Error; and for "= txtTotalPhoneUse", I get #Name.
CustomerRoomUse and txtTotalPhoneuse are from the subform that was dropped into the customer form in a previous step. It shows that explicitly when designed sbfCustomerRoomUse on the main that CustomerRoomUse come from a subform. This does not seem to need to be done with txtTotalPhoneuse, and I am not sure why. Neither one gives me a desired calculation result.
I have an odd problem that has stumped me for several days. I'm working on a form that contains a chart. The chart is based on a query, which is based on another query, which is based on a table. In the top query, I need to put some calculated fields that operate on other fields. But when I try to multiply two fields together, I get Null. I'm pretty confident that the fields I'm operating on are numerical.
I'm hoping this is a no brainer...I am a complete newbie and self taught so apologies for not knowing the correct techie terms!!
I have a db with products...
Each product has a price (to customer) and cost (to me the seller)
What I want to work out is the margin i.e. price minus cost divided by proce multiplied by 100 to give a margin in percentage terms.
The data is held in a table with a record per product with the price and cost..
I want to build in another fieled per record that calculates the margin...
Thanks very much
Jessica
(I would also like to be able to work out decreasing margins if I was to extend say a 10% or 20% discount to the customer but I guess I shoudl walk before I run!!)
Hi, I have a database and on one table I have dates stored for certain jobs. I was wondering if anyone knew how to automatically calculate an end date if the start date and duration is entered!
Ok I'm really new at using access so go easy on me. I am trying to write a database to keep 30 measurements of a part grouped by lot number and then calculate the standard deviation, mean and a few other calculations, however I am unsure about how to do the calculations in access.
I would like the database operator to be able to enter the data then print out a report per lot, with the entries and the calculated answers.
I'm just unsure where and how to do the calculations... any help or suggestions?
I'm trying to a create a report to list results for a running club based on series-to-date. To do this, I allocate points to the first 100 runners to cross the line in each race. The winner gets 100, second place 99, and so on with the 100th person getting 1.
In the database i have 1 table holding member details, then one table holding races. I also have a table linking the 2 called race_entry so i know what members have entered for which races. I have one other table called race_result that links the runner to a race and holds the position they finished in the race.
How could i use the data in the race results table to add up all the points they earned by looking at their finishing position in the races they run and then listing the points in order in a report.
I assumed it wouldnt be necessary to have a point field in the table as its deriveable.
This is more than likely simple for a lot of people out there but it has me stumped. I have a form that has a two combo boxes with dates in both ( so the user to pick from and to dates) now I am always going to be adding more dates as time progresses. I need the next form to add the info with the dates no mater what the user picks. For example I am going to (once a week) be adding new info to the table.The end user is going to pick 06/24 (to indicate the end of the week) in both forms or 06/24 in the from box and 07/01 in the to box. In all situations I need the next form to add the data together. Sorry for the long post but didn't know how to state it any simpler.
I am a beginner with Access and was wondering if someone would be so kind to give me some pointers
I have created a form where the user can select which dates they require a hotel for the evening. I was looking for some advice on how I can go about putting an area on the same form which calculates a sub price for the days they have selected. If I am not being clear then ask for more details.
I need to be able to use some functions available in excel in an access 2000 database. These include SUM and IF functions. If any one can help me figure out how to do this any help help wouold be greatly appreciated
Hi I would like to manipulate some date information. I have a start date field and an end date field and I would like to draw up a schedule for payment where the Acess takes the finished date and the start date to get total days appart then devides this by a value set by the operator. say If the operator wanted 6 paymes then my total days would be devided by 6 giving me the number of days to add on to the start date. Then with these dates a schedule is made up and the code I have tried looks something like this.
Dim valuation1 As Date Dim valuation2 As Date Dim valuation3 As Date Dim valuation4 As Date Dim valuation5 As Date Dim valuation6 As Date Dim valuation7 As Date Dim valuation8 As Date Dim valuation9 As Date Dim valuation10 As Date Dim valuation11 As Date Dim valuation12 As Date Dim startdate As Double Dim findate As Double
Dim valcounter As Double
'retrieve start date and end date startdate = CDbl(Me.Start_Date) findate = CDbl(Me.Completion_Date)
'calculate evaluation periods Dim valCount As Double Dim valDays As Double
Select Case valcounter Case "1" Me.valuation1 = startdate Case "2" Me.valuation2 = startdate Case "3" Me.valuation3 = startdate Case "4" Me.valuation4 = startdate Case "5" Me.valuation5 = startdate Case "6" Me.valuation6 = startdate Case "7" Me.valuation7 = startdate Case "8" Me.valuation8 = startdate Case "9" Me.valuation9 = startdate Case "10" Me.valuation10 = startdate Case "11" Me.valuation11 = startdate Case "12" Me.valuation12 = startdate
I have a question that I can't seem to figure out. I am trying to create a form in which there are three major fields. 1) Value 1 2) Value 3) Sum of Value 1 & 2. I want it so that two fields are added up and then the sum, which will populate in the third field, will be stored in a table.
Does anyone have any suggestions on what I can do? I am fairly new to access and haven't had much luck finding anything on the net.
The fields include both date and time (date and time are in the same field) i.e. “6/26/2006 4:23pm”. The next field I need to calculate the duration, basically one field minus another…anything I’ve tried will only calculate the time difference will not factor in the days. For example, if it has been 52 hours (2 days, 4 hours) it will only say 4 hours. A few of what I’ve already tried are below. And I’ve also tried an elapsed time expression.
I am currently setting up a data base for my work and was wondering if there is any way to do the following calculation:
I have a database of automatic doors that are contantly being repaired and i want to keep a record of the accumulated costs involved with this.
I have set up a form to update each door and its accociated repair cost, the problem is when i enter the new repair cost access replaces the current cost with the new and i want it to be added to the current cost so the accumulated cost can be bulit up over time.
I've read the posts regarding not store calculations. However, I was told by IS to store the mileage IRS deduction as it changed 3 times last year.
Any idea's how to handle this? I need the table to remember how much $$ was paid out in mileage expense. I had set up a field called mexpense and mileage, where =[Mileage]*0.375.
Just like to thank you all for all the previous help I have recieved from this forum.
I have reached another snag :eek:
I am trying to show a field in a form which will be the sum of some data in a sub form ( Which hols data in a seperate table )
Anyway,
The Relationshiop to the subform table is a 1-many from my main table. This has a ref number which is what makes the 2 link together.
Im trying to find the money value of feild X all of the records related to the reference number, then this needs to be displayed in a query so I can show this value in a form.
This is what I`ve tried and it just displayer #error =Sum([Cost £]) I would have though this would work, as i have used this before to calculate the running total of another field. Does this not work because its a subform im trying to get the data from ?
I`ve attached a copy of the database with some sample data in it just incase I have not made myself clear. (A2003)
Thanks in advance for any help/advice.
Max
[update]
Quote: In the report, do the SUM in the subreport, set it to 'Invisible' (in the properties box), and reference it in the the main report by adding an unbound text field and setting its Control Source to: =Name_Of_Your_Sub_Report.Report!Name_of_the_Invisi ble_Totals_Textbox
I have done the above, but made changes like below: =[Materials & Labour subform]!Total
