Hi Vladimir,

Thanks for the response! From my menu I was starting the form using DO FORM formname. When I used this the app object was not adding the form to the array (but I still can't figure out why the form object wasn't available elsewhere). I changed my menu command to goApp.DoForm("formname") and now the form is added to the array and available to my code.
