Thanks for the suggestion. I put in a NODEFAULT statement and was able to find out what I was doing wrong. Now only one small problem remains.

Whenever I click on the initially inactive page (Page2), the grid has focus but the focus rectangle is on the caption of Page2. When I leave Column 1 focus goes back to Page2. After that everything is fine. Also, if I click on Page1 then again on Page2, there is no focus rectangle is on the caption of Page2.

Is there any way I can get the focus to be fully on the grid the first time I click the page (ie no focus rectangle on the caption)?
