Just wondering if anybody could help me on this. I have encountered a problem in producing a report based on my main form (recordsource: tblStudents) and subform (recordsource:tblStudentsClasses), which are joined through their respective StudentID fields. My problem pertains to the fact that I just couldn’t seem to find a way to make my report produce a calculated value using an unbound control. I need it to show the average grade a student gets every semester by multiplying his individual class grades against its corresponding credit units and then add them together, and divide them against the sum total of that particular semester’s credit units. For example, a grade of 1.0 for psychology 101 multiplied by that subject’s 3 credit units + a grade of 2.0 for chemistry 101 multiplied by that subject’s 5 credit units and then divided by the sum total of those two subject’s credit units of 8.
I kinda find it complicated because each semester is made up of between 1 to 10 classes, so it would be inappropriate to just put the one average computation on a footer since each semester has to have an average grade of its own. Tried lots of procedure already and couldnt make anyone of them work. Another fact is that a credit unit of –3 and grade of 5.0 shouldn’t be included in the computation at all. And some of my data are supplied by combo boxes in the subform – cboCreditUnits and cboGrades (rowsources: tblClasses and tblGrades). How should I go about this all? Any ideas will be highly appreciated.
They want me to add to it, where if [Text106]="0",[Reserve]-[Text52], otherwise it's [Text106]="0",[Reserve]-[Text106].I am able to do this second part OK with
I am not sure whether I posted in the right place but here's the deal: I have a form and a subform based on two tables and on the form I create a mathematical expression concerning a field which is based on another. The results are correct but of course the values in the table remain the same (null). Is there a way to have a formula in the table and then when I create the form based on that table to have the formula ready? BTW where are the data stored if they are not stored in that table?
i have been struggling on this database that i am developing for a while and i haven't found a solution yet.
i have a Two tables
Table 1 "Attendance" with fields Attendance ID, Hours, Group ID.
table 2 "Days" fields, Day ID Week beginning Monday Tuesday Wednesday Thursday Friday Hours
now i have created a form from these two tables, and what i wanted was each day of the week i will input a value under the day and i wanted it to be added up and then the result outputted to the "Hours" Box.
My dilema is that although i have figured out how to add up the fields in the form view by changing the Control source for the Hours box to something like =[Monday]+[Tuesday]....[Friday] this will only display the value in form view, the table will not update. i guess this is because the control source is not relating to te table anymore.
so if someone has some other ideas i would appreciate it. regards Yusef
Below is the code I have created to calculate the values "CalcValue" and "CalcWork". The values for AssignValue, AssignPriority, Complex, Effort, Goal are all assigned by the selection made in the referred to/related combo boxes. However, the caluclated values return the concatonation of the intergers and not the sum of the integers. Additionally, if I am to use the CDec() function how do I specify the number of decimal places?
what am I missing here?
thanks!
Private Sub cboAssignPriority_AfterUpdate()
Dim CalcValue, AssignValue, AssignPriority, Complex, Effort, Goal, CalcWork As Integer
I have a table with numberous records with Values in a number of fields. In a report I am showing all these records but at the end I want to tally the values.
Whats the best way to do this?
I thought of placing a text box in the form that will run some code to calculated the total....
I have a report that contains 3 subreports with a calculated total text box in each. I am trying to calculate the total of these text boxes from the subreports in the main report but I keep getting an error message (#Name?). Is it possible to calculate calculated sums from subreports in a main report?
I am pretty new to access, I will get right to it.
I am scoring rating scales. I want to be able to enter just the responses from a person, say on 80 questions (preferably into a form), where all the answers are 0 to 3 and have Access add the questions into the right groups to calculate all the sub-scores of the rating scale. For example, Scale A may consist of Questions 1, 6, 15, 29, 35, and 70 I need access to add those up and save them so I can use them in a report. I also need access to add the frequency of certain questions that were responded to with the answer 3. I have gotten Access to calculate the scores in a form by adding extra variables to the form, erasing the variable name out of the white box and putting in the syntax =[Q1]+[Q6]+[Q15], etc. in place of a variable name but it just sits there on the form and doesn't store it anywhere. Thanks
Hello all. I hope someone can lend a helping hand here. I am trying to create a query that will calculate a 24 hour value for every day of a month. For a month a go out a read meters. I need to get the difference of two readings by subtracting the first day from the second day and so on until I get to the end of the month. So, Day2-Day1=24 hour value, Day3-Day2, Day4- Day3... I have this in a spreadsheet but can't seem to grasp it for a query in a database. I would appreciate any help. Thanks.:confused: :D
Hi, I wonder if someone can help me with the following problem:
I have a table with 2 columns,start time and end time, both containing time values in a four digit format, eg 0930 being 9:30am etc.
I have made a query to convert these into the standard format (eg 0930 becomes 09:30), using left/right and & functions.
Now I use the timevalue function to convert the string , eg 09:30m into a recongnised time value.
The problem is now I want to find the difference between the start and end times- but when i try a simple end_time - start_time formule it returns a long number which i dont understand, rather than just giving me the difference betwen the two times.
Im sure there is a simple way to do this which I dont know, can anyone help me out? Thanks in advance!

I have a query that must calculate the different between values in two different records, based on the date.
The underlying ORIGVALUES table contains:
Date; Value; Diff 1/10/15; 100; (this is what I am trying to calc) 1/11/15; 101; (this is what I am trying to calc) 1/14/15; 102; (this is what I am trying to calc)
What is the best way to have each record calculate the selected date value divided by the prior date value)? E.g.
For 1/11 the math is 101 / 100 (so the 1/11/15 record would show the result of 1.01) For 1/14 the math is 102 / 101 (1/11 to 1/14 represents a weekend)
I could copy the prior day values to the current day records and do that math easily but that is very redundant.
I am using workdays to calculate time passed between two dates. I also have a table for Holidays that I don't want counted as work days. This is working well, but I would like my queries to show a null value instead of showing #Error when a date field is empty. Here is my coding in my Module.
Option Compare Database Option Explicit Public Function Workdays(ByRef startDate As Date, _ ByRef endDate As Date, _ Optional ByVal strHolidays As String = "Holidays" _ ) As Integer
I'm trying to create an expression to calculate percentage.
The fields, Value A and Value B might both have null values, but I do not want Access to treat nulls as zero (as in the Nz() fn). How do I get the expression to exclude any nulls and not calculate for those rows, but set the calculated value for a row with null A or B to zero.
I want it to set no calculated value to zero so I don't get overflow errors and can therefore order the data by the calculated field.
If I have left anything off that may be vital please ask and I will supply the info. I need this info ASAP though. I think the answer has something to do with the Date() and CurrentDate() but I have no clue. Please let me first know the queries I need to run and that should be it. I just need to put MTD and YTD Sales in a report.

I am currently using Access 2007 and have created a huge database for our investment managers to calculate the income based on percentages. The percentages are created in Excel. I have uploaded into the database both the June and the July percentages. When I run the query for my report using the date range for June, it works fine. When I request just the July information (entering the date range for July) the June data is doubled on the report.
In Access 2010, I have a simple sub-report I use to count a field. Works perfect by itself. However, when I place it in the main report the results change. And it doesn't matter where I place it in the Main report, it still returns a low count. Is there some filter I am missing?
I need to create record totals and grand totals on a report where I count up the # of Yes's and No's across 10 fields. I've already created calculated text boxes that come up with the record totals. What I can't figure out for the life of me is how to create a text box calculating the grand total based on the previous calculated fields I created. It seems that access isn't letting me sum a field I created on the report. Do I have to create a query first? Thanks.
I have two issues with the report generation from a query:
(i) Sometimes blank values appear in the report in the serial number column generated dynamically (setting the control source property =1 and running sum = overall), but when clicked inside the particular box, the correct serial number appears
(ii) When grouped on a field, the particular field value appears sometimes more than once in the report inside the same group.
I have a report that is returning percentages based upon other calculated fields. Some of the percentage fields are showing #Num on the report. I've found this is due to one of the calculated values being zero.
I'm having problems with a count expression in a report. I have a series of items listed, with subdata against each one, in some cases this subdata is one rows, in others it is many rows.
Anyways, having listed these items and there subdata sets, I want a count of the number of items listed.
Unfortunately, a count on Equipment ID returns the total number of sub data items listed, as for each sub data item, the Equipment ID is associated. Is there a way of making the COUNT expression count exclusive values?

I am trying to generate a report, or even a word merge doc, that will print only the fields containing values above "0". I have to print a one page benefits report for each employee, yet not everyone has values in each available field. On each report, I only want to show the fields that actually pertain to the employee. Is this possible?
I have tried doing this as a Word merge, but the field names do not show up, only the values...I have been struggling with this for over a day...please help!
