Hello:

I have a form that users must mandatory entries into textboxes
before they exit the screen and move on to another screen.

For example:

If empty(act_plan.startdate)
=messagebox("You must enter a Startdate for your Intervention!", 48, "CATS")
this.parent.text1.setfocus()
Endif

I have this code in the save button and if nothing entered it sets focus to that field until something is entered. I also have this code in the exit button on the form. If they inadvertly hit the exit button I get the message, it doesn't set focus to the textbox
and continues on and releases the form.

How can I ensure that they fill this textbox and not exit the screen
screen? Does this code belong in the "valid" of the textbox as well?
Any input would be appreciated.
Thanks.

Sheena
