Nadya,

why not simply

replace (this.parent.parent.column2.text1.ControlSource) with curTowns.ccode in (left(this.parent.parent.column2.text1.ControlSource, at('.', this.parent.parent.column2.text1.ControlSource) -1 ) )

this.parent.parent.column2.text1.Refresh()

and correction to the code below, replace should read (since the table may not be selected)

replace (this.ControlSource) with this.Value in (left(this.parent.parent.column2.text1.ControlSource, at('.', this.parent.parent.column2.text1.ControlSource) -1 ) && or whatever the tablename is

All other problems, which I mentioned in my reply to Cetin, are more important. I'm thinking, that combo in a grid is a bad choice. May be I have to create a container based class instead?
