I have a text box. I need to validate the value entered. If the value entered is invalid. I need to open a form containing four table options for a user to select.

First I used DO FORM myform in the text box valid method. But after it opens the form, the focus returns to the text box and the form hides behind the screen.

Second try I did is that I build the formset which contain both the data entry form and pick table option from. I tried in both valid method and lostfocus method, put in setfocus method of an object on the pick table option form. The pick table option form just flash and focus returns the text box.

What should I do to make the pick table option form staying on the top of the data entry form?
