I have a form with a grid. In the grids .Column4.txtHours.Valid is the following code:

This.Parent.Parent.Column3.txtAmount.Value=ROUND(This.Value*Billing_Rates_View.Maxofbill_Avg_Rt_Amt,0)
This.Parent.Parent.Column3.txtAmount.Refresh

After the event fires a series of X's (i.e XXXXXXXXXXXXXXXX) appears in the upper left corner of the form.

In the DE.BeforeOpenTables() I have,

SET TALK OFF
SET TALK NOWINDOW
SET ECHO OFF

Any ideas on what this is from?
