Perform the check again when the "OK" button gets clicked and stop the user. I also like to use the following lines of code to highlight the offending textbox: [VBA] With txtFileName .SelStart = 0 .SelLength = Len(.Value) End With [/VBA] --JP I think it’s more appropriate to create a function that validates your form fields, then either
