The following is the code in the valid event of a combobox :

IF this.ListIndex = 0 AND thisform.nformstatus > 0 && insert or edit mode
lyn = MESSAGEBOX("This carrier is not in the database, do you wish to enter them ?",4+32,"Carrier information")

IF lyn = 6 && yes
DO FORM carrier NAME carrier2 LINKED WITH this.Value
ENDIF

ENDIF

The messagebox comes up but when you select yes to enter the data the form just flashes on the screen and closes immediately.

Any help greatly appreciated.
