hello,
have attached database-
open database and a form comes up- click Item code and name button-
( enter 101 for item code and jim for name)

a Form comes up that displays avg time it takes Jim to work on item code 101-
question:
Is there a way to display also on this form? the total avg time it takes all names listed in the table?
Thank you,

On your Form2 you can create a text box control with a Control Source expression of:

=DAvg("[Time Spent]","Table1")

You could use a DSum:

Msgbox DSum("[Time Spent]", "Table1", [Item Code]='101')

Or if the form is bound to that table, and you want too get the Item Code dynamically:

Msgbox DSum("[Time Spent]", "Table1", [Item Code]='" & Me![Item Code] & "'')

"You could use a DSum"

I thought the Questioner wanted the average of all in Table1? ... but it is unclear about whether or not to filter on the item code.

---

So, if filtering is the desired result, then you can apply the filter LSM created in the DAvg() function:

=DAvg("[Time Spent]","Table1", [Item Code]='" & Me![Item Code] & "'')

sorry about the error.  the Me keyword is valid in VBA, however in a Control Source expression, you use [Form]

=DAvg("[Time Spent]","Table1", [Item Code]='" & [Form]![Item Code] & "'')

or, you  just drop the form reference since your scope is the current form ...


=DAvg("[Time Spent]","Table1", [Item Code]='" & [Item Code] & "'')

thanks - you know I am still getting error-
can you insert code into txtbox on form and attach db back here?

also just to confirm I am doing this right -am inserting code into the control source of the unbound textbox on form ( form2)
thanks

This ...

=DAvg("[Time Spent]","Table1", [Item Code]='" & [Form]![Item Code] & "'') 

Open in new window


Should be this ...

=DAvg("[Time Spent]","Table1", "[Item Code]='" & [Form]![Item Code] & "'") 

Open in new window


Pay close attention to the quotes!  It seems that LSM inadvertently did not balance the quotes and I copy pasted from him <dazed> ... So, I think I got it right this time!  {note: I am not in a position to post a sample, so hopefully this will do the trick!
