Dynamically entering query criteria on Form

[Gwen]

Hi,

Please help

I have written code to dynamcially enter information in
text boxes when the form opens to be used as criteria for
a query. However the query is not getting the info. When
I manually enter the info in the text box the query runs.
What am I missing ? Below is the snippet of code:

For i = 0 To usr.Groups.Count - 1
grpname = usr.Groups(i).Name
strcriteria = strcriteria & "= """ & grpname & """ or "
strcriteria = strcriteria & varname
Next i

Me.criteria = strcriteria

thanks

Gwen
