# Calculating in Access form

Posted on 2007-11-14

Hi,

I am trying to set up a fairly simple database to record safety issues. In the entry form, I want the user to enter frequency (1-5) and severity (1-5), and have the form calculate the resulting score (multiplying the frequency and severity). This is, of course, easy to do in the reports, but the client would like to know if this can be calculated in the form as well. That way the user can see the score live as they enter the frequency and severity.

Is this possible, and if so, how?

Thanks,
Alex

In code behind the form of one of your combo boxes (air code, so you'll need to change a bunch of names)...

Private Sub SomeControlName_AfterUpdate()

'Bail if there is no value in the Frequency text box
If Nz(Me.Frequency, 0) = 0 then exit sub

'Bail if there is no value in the Severity text box
If Nz(Me.Severity, 0) = 0 then exit sub

Me.ResultingScore = CInt(Me.Frequency) * CInt(Me.Severity)

End Sub

{slight correction}

In code behind your Frequency and Severity boxes...

Private Sub Frequency_AfterUpdate
Call CalculateScore
End Sub

Private Sub Severity_AfterUpdate
Call CalculateScore
End Sub

... then as a separate sub ...

Private Sub CalculateScore()

'Bail if there is no value in the Frequency text box
If Nz(Me.Frequency, 0) = 0 then exit sub

'Bail if there is no value in the Severity text box
If Nz(Me.Severity, 0) = 0 then exit sub

Me.ResultingScore = CInt(Me.Frequency) * CInt(Me.Severity)

End Sub

You can do it the same way you do on the report.
Create a textbox and set the value to "=Me.Frequency*Me.Severity"

Thanks all who replied and sorry for the slow response. I didn't get a chance to work with this until today. JimFive, your solution did what I wanted and is about as simple as it gets! Thanks for your help.

The other solution (JimHorn) probably works too, but I do not have much experience working with coding. It wouldn't hurt for me to learn about that - any pointers toward a good starting resource would be appreciated. Thanks again.
