Hi Hilmar,

Thanks for the quick reply. The .Value is {} and I even set the .Value = DATE() in the Form.Init.

However, you're second suggestion was the issue. I changed SET FILTER TO Date = This.Value to SET FILTER TO Date = ThisForm.txtDateFilter.Value and now it works fine.

Tx.

>The type mismatch probably means that the date field is of type date, and the TextBox, of type character. Make sure it is of type date, or do a conversion. To make the TextBox of type date, you can assign it an initial value of {}.

>Also, "This.Value" will very likely be meaningless a little later in the program. Therefore, you may have to use a variable instead.
