Summing A Calculated Field
Jan 17, 2005
Hi,
I want to sum a calculated field on one of my forms. The field is calculated by multiplying the cost of a good by its quantity. So far I have been unable to sum it. Does anyone know how I can do this?
Here is a link to what the field is related to just so you people know what I am talking about: Project (http://www.access-programmers.co.uk/forums/showthread.php?t=78815&page=1) ...basically I have fixed all the problems mention in that thread. All that remains is this field. I will attach my project in case that helps. (the calculated field is in the Treatment Form) Thanks in advance :)

I have a report that has four fields: Item, Qty, Price and TotalPrice for each line in the detail section. Total Price is calculated by multiplying Qty x Price. The text box name that holds the Total Price for each line is txt_TotalPrice. I want to have a Grand Total in the report footer. I placed a text box in the footer with the following expression: =sum([txt_TotalPrice]). When I run the report Access prompts me for the parameter value of txt_TotalPrice. I've been trying to solve this for quite a while now - but I'm totally baffled.

In my tables i have used calculated fields. one of the fields is to "total expenses." In a report, i need to show the sum of all the "total expenses", the filed populates in the report but the cents are missing. for example if the amount is 6080.40 it shows as 6080. how can i get around this? I have tried changing the decimal point value to 2 at which point the value turns to 6080.00 when it should be 6080.40 (i am a beginner at this i am assuming the answer will probably involve c++ or visual basic's, two concepts i am not familiar with.)

I have a sales form. The sales form has many Call, Meetings and Emails linked to each sales record. I want to total all the number of calls, meeting and email records related to the sales record to give a total- Touches.I've created 3 queries;
1 - Counts Calls
2 - Counts Emails
3 - Counts Meetings
These all work fine however when I combine them to attempt to count the results it doesn't produce the correct results.I have a second query as well (no pun intended).
I am trying to sum together a column that has values in Time. The results displays as a decimal. How can I have the result display as a Time i.e. 1:20 (1 hour 20 minutes).

I have 2 field in a table - CourseMarks and ExamMarks. I am making a query to sum these two values. My code entered through the expression builder is Total: [CourseMarks]+[ExamMarks].
When the query is run there are no results if both fields have a score, but If there is a score in the CourseMarks field and none in the ExamMarks field the CourseMark is returned.All the field value data types are interger.

I am trying to create a sum of a field called ec2mo where mopp is between 0 and 2 and then another sum when mopp is between 2 and 4, etc... I've tried a number of different things, but it doesn't seem to work - instead i get a single value for each field (i'm assuming because there are different values for mopp and many other fields)... I've attached the db with just that table.
Thanks very much for your help!
P.S. I'm not really at all good with using SQL so anything that can be done in a regular query would be most helpful!

I have two Numeric fields in my Table, MCRefill and MCTot.
Actually MCtot is the sum of all MCRefill for a given Cust_ID
I have the following expression in the Default value of MCtot in my form showing both the fields
DSum("[MCRef]","Miracle_Cloth_Main","[Cust_ID]='" & [Cust_ID] & "'")
Somehow it doesn't up in the record when you load the Last record for a Cust_ID
Can someone please help ?

I have a table called Products which has a field called "Product ID" and a few others. I have another table called "Sales", which has a field called "Sales Date".
There will be different dates where the products are sold. Here's my problem: I'm trying to make a query to find out which products make the most sales. However, doing so will also display the products separately by their sales dates. So for example, it'll show...
Product #10 / Jan 1, 2013 / 100 Sales
Product #10 / Jan 14, 2013 / 21 Sales
Product #10 / Feb 11, 2013 / 44 Sales
Product #11 / Jan 5, 2013 / 201 Sales
Product #11 / Mar 13, 2013 / 444 Sales
I'd like the products to be together so product #10 would give 165 sales for example. In the Query, Product ID from both tables are connected.

Here is a link that explains a little bit about it: [URL] .....
However, I'm having a problem with summing an entire field. Access does not have a DProduct() function, so it makes the math of "taking the Nth root of a product of 'X' numbers" kind of impossible without writing a custom function.

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.
I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.
Does anyone know how to correct this? Thanks in advance.
:confused:

Table1 contain Two fields (3Months) and (6Months)
Table2 contain Two fields (3Months) and (6Months)
the table 2 is the source of a form that will let the user change the numbers. table 1 should change Date1 and Date2 Fields based on the two fields (3months) and (6months) if i want to make a lookup wizard it should be changed manually and if i make a calculated field i can't find other tables in the expression builder

I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:
10Jul15: Sales
and then adding Criteria like:
EndDate = #10/07/2015#
It doesnt work.

I use access 2010.
I am assuming by the error code, one can not use a calculated field to calculate another field.

Hi,
I have a calculated field in a query that concatinates an order number prefix and the part number to give the order number:
OrderNum: [OrderPrefix] & [PartNum]
There are 2 tables:
tblPartsList
PartNum
PartDesc
tblPartsListCategories
OrderPrefix
OrderNumCategory
This works fine except for one of the categories. For the third category there are no entries in the tblPartsList - because they are miscellaneous.
How do I change the calculation so that it works as above where there are corresponding Part numbers in tblPartsList and otherwise gives me the order number and any 2 digits e.g. something like [OrderPrefix]*
Having been trying to do this for ages but having trouble with syntax.

I am new to Access so please be gentle.
I heve started a new table and one of the fields is Date of Birth.
I want to have another field that looks at the data in DOB and calculate the age, I believe that this can be done with funtion datediff, but the layout doesnt look for other fields, it just looks for a date and the Now statement.
Any ideas on how to make this work? does it have to be a querie?
Mant Thanks

This seems a daft question but I have searched the forums and can't find an answer so I hope someone can help me.
I have a table: Register(RegID, Pupil, Activity, Duration, Preparation)
I have a query that I want to calculate the total hours the pupil has spent on activities.
The Duration and Preparation fileds are held as number of minutes so for a 1 hour event the number 60 is held.
I have a query with 4 fields:
Pupil
SumofDuration
SumofPreparation
TotalHours = ([SumofDuration]+[SumofPreparation])60
The problem I have is that TotalHours is calculating as an whole number.
e.g. I have a Record
Pupil = 701
SumofDuration = 270
SumofPreparation = 0
TotalHours = 4
But I want TotalHours = 4.5
I have set the Duration and Preparation field sizes to Decimal and Format to General Number.
I don't know what else to try.

Can anyone tell me why this won't work? It calculates the 2nd argument (reduction_man) but not the first (reduction)
I have tried both of these and still can't get it to work.
=IIf([reduction])>0,([reduction]*[2004volume])/(13-[cutinmonthnmbr]),([reduction_man]*[2004volume])/(13-[cutinmonthnmbr]))
=IIf(IsNull([reduction])=False,([reduction]*[2004volume])/(13-[cutinmonthnmbr]),([reduction_man]*[2004volume])/(13-[cutinmonthnmbr]))
Thanks!

Hello Guys,
I am trying to do the following in a form.
1) (Travel hours + work hours) * dollarperhr to get the "Total" bill to a customer.
2) The results will be put in a field "TotalDollars" that is a part of a table.
Please help.
I tried to put an event (on change) on the "dollarperhr" box so that after entering the values in "travel hours" + "Work hours" * "dollarperhr", the calculation will be done to populate "TotalDollars", but it didn't work.
please help
