I hae had this problem before, and got it fixed, but I dont remember how I did it as it was a long time ago. I have 7 textboxes on the page and all but this one wont show the value. For example, I have a checking when someone hits save:

'Functions.Alert("You must select a valid Pay To to continue")
txtPayTo.Focus()
Exit Sub
End If
and it always gives me the "error" message and will exit the sub
