Calculate On Form

Mar 9, 2005

Hi,

I have a from with 3 fields on it where users can enter numbers of boxes attached to a booking.

Each field stands for a box of a certain type.

E.g.:

20's ==> 1
40's ==> 1
45's ==> 1

Now, I want to calculate a total based on 40 being 1, 20 being 0,5 and 45 being 1,125.
The total in this case would be:

2*20 = 0.5
1*40 = 1
1*45 = 1.125

Total: 2.625

Is this possible, and, if yes, how do I insert this calculation?

Don't know if this is clear enough, if someone has any questions on my goal here, please ask me to clarify...

Thx once more,

Lion85heart

Calculate Due Date On Form

Mar 27, 2006

I have a form (frm_Active) that reads from a query (qry_Active) based on a table (tbl_Data). The form/query/table has the following fields:

EVENT DATE
START_DATE
REVIEW_DATE
APPROVED_DATE
POST-REVIEW_DATE

When I add a new record, I would like for the default dates to be populated based on the EVENT_DATE. For example, if I enter 1/1/2006 for the EVENT_DATE, I want the

START_DATE = +7 days
REVIEW_DATE = +55 days
APPROVED_DATE = +60 days
POST-REVIEW_DATE +180 days

I tried to do this in the table as the "default value" and it would not accept it. I don't think I can do this in the query because the query is basically displaying the table and I want to be able to manually enter a different date if needed so it will be stored in the table. I tried this on the form in the "Default Value" field, but it is just blank when I enter a new record and enter the EVENT_DATE. However I am not sure I am entering the formula correct. Can someone tell me what is the best way of doing this and what the correct formula is?

Thanks,
Jim

Calculate Percentage On Access Form

May 4, 2006

Hi, Thanks in advance. I am trying to calculate percentage, it has to round to the nearest, and also if the percentage is greater than 100 then it has to write 100%.
formulae: c=(a/b)*100,
example: c=(8/3)*100 =266.66% but this is more than 100% so i need this as 100%
example2: c=(2/3)8100=66.66% but i need it to round as 67%

i've 3 controls on a form a,b,c. so c has to calculate by itself when they enter data on a and b.
thanks,
sam

Forms :: Form Won't Calculate Totals

Feb 5, 2014

I am having trouble on the Work Orders Form to get the SubTotal to calculate correctly.

The SubTotal Control Source is:

Code:

=DLookUp("[Services Total]","[Services Total]","[WOrderID] = '" & [txtWOrderID] & "'")+DLookUp("[Parts Total]","[Parts Total]","[WOrderID] = '" & [txtWOrderID] & "'")

The Form Record Source is:

Code:
SELECT DISTINCT [Work Order].*, [Payment Total].[Payment Total], [Services Total].[Services Total], [Parts Total].[Parts Total] FROM (([Work Order] LEFT JOIN [Parts Total] ON [Work Order].WOrderID = [Parts Total].WOrderID) LEFT JOIN [Payment Total] ON [Work Order].WOrderID = [Payment Total].WOrderID) LEFT JOIN [Services Total] ON [Work Order].WOrderID = [Services Total].WOrderID;

why my form won't calculate totals?

Calculate Distance Using Fields In Form?

Sep 28, 2013

However Instead of entering the postal code continually or selecting from the combo box. How do I set zipcode 1 and zipcode 2 based on fields in a form. I would like to use the current FROM (Default zip based on the current job in form) and TO zipcode [Project Postal Code] that is on the form at that time. Not necessarily combo box.

Currently you have

zip1 = Me.Combo2.Value
zip2 = Me.Combo4.Value

I want Zip 1 to be Default zip (however I can still change it if needed) ZipCode field is [Project Postal Code]

Here is the full code:

Private Sub Command6_Click()
Dim zip1 As String, zip2 As String
Dim sResponse As String
Dim sLink As String
On Error GoTo Command6_Click_Error
zip1 = Me.Combo2.Value

[code]....

Calculate Last Record Value Plus 1 / Display Result On Form?

Nov 18, 2014

I'm trying to use the job number field, which is my primary key in my table, to auto assign the new job number on my Forms. Currently, I have to enter a new job number manually, and it has to be unique because that is the way I have it set. I can't use autonumber because Access does not allow you to select what number you would like to start from, which would not play well with my current job numbers.

Basically I need Access to get the job number from the last record and add 1 to it, or just find the last / highest current job number and add 1 to it.

I created a query (qryFindJob#s) that list all of the Job Numbers, but I'm not sure how to add the query results to my Form to display the Job number + 1. I created a text box, typed a simple expression in the control box to see if I was on the right path (=[qryFindJob#s]) but I keep getting a #Name? error in the txt field.

Forms :: Calculate Passed Working Days And Show Them In A Form

Jul 8, 2015

I need to calculate the passed working days and show them in a form. I should be also able to use the number in a query later on. in excel I use the formula to get the days passed:

Code:
=IF(ISERROR(MATCH(F10,Dictionary!C:C,0)),NETWORKDAYS(D10, TODAY(), Dictionary!$E$2:$E$43),"Status Excluded")
D = "Date_uploaded" in access table "tbl_All_Cases"
F = "Status_Case" in access table "tbl_All_Cases"
c:c = dictionary case status
E:E = dictionary holidays

"Status Excluded" will show up in the cell if a case has one of the status from the dictionary..I created a table: tbl_Dictionary where there are 2 fields: "Case_Status" and "Holidays".How can I translate the above formula into something that access will understand?

Excel Can´t Calculate.

Aug 6, 2006

HI,

Excel is having difficulties calculating a workbook of mine. It complains about cirkular references, so I had to set the iterations manually.

The workbook holds about 5000 records and I´m using a cosinus function.

The thing is I don´t know what to do. Excel calculates the workbook, but it doesn´t do it right. What setting should I use with the iterations?

I´m thinking of running it in excel 97. Will that help?

I really need to be able to run this workbook. Does anyone have an idea?

Fuga.

I have two databases and one of the PC's here at work can’t use some of the items in the database like on one of the databases there is some formulas in text boxes and that PC won’t calculate what’s needed in them and every PC in the plant will except for this one PC.

Calculate Commissions

Jan 15, 2007

Hi

I am very new to databases, and think i am a bit over my head. I am doing a database for vacation rentals, and am trying to calculate commissions, basically i wanted to have a set of checkboxes, labeled 10%, 15%, 2.5% and $25, with any combination of these checkboxes being able to be checked.

i want the query to work like this:

If the 10% checkbox is checked i want the query to take the SubTotal for the reservation, and calculate 10% of that number. if the 2.5% checkbox is also checked, i want the query to calculate 2,5% of the reservation and add it to the commissions total (10% + 15%)

I think(hope) that i explained that clearly? Can this be done?

Thanks for your help!
