Code in the Activate() event of my page frame:

WITH THISFORM.pgfValid.pagListe.grdListe
   .RecordSource = "TempListe"
   .colListe.ControlSource = "TempListe.cLiNom"
   .colDate.ControlSource = "TempListe.dAppel"
   .colTel.ControlSource = "TempListe.cTel"
   .colPrenom.ControlSource = "TempListe.cCustomerName"
   .colRespCode.ControlSource = "TempListe.cCodeRep"
   .colAgentNb.ControlSource = "TempListe.cNoAgent"
ENDWITH

This was working fine until I deleted 2 columns from my grid (not appearing in the code above).

Now, whenever the Activate() event fire, I get the message "Unknown member COLLISTE". I get this error message for each of the 6 columns of the grid.

In the debugger, I can see that the name I gave for the columns have been replaced by Column1, Column2, etc. They still appear with the correct name when I open the form (colListe, colDate, etc.)

I even recreated the grid from scratch, but to no avail.

TIA
