switching between forms in developer?!

I need to button on a form to switch to an other form. I use the trigger 'when button pressed' and I put there open_form('other_form'); But somethimes this works and somthimes it just dont. I really really dont know what the hell is wrong. The message I get is 'cannot read from form other_form'. I there maybe a good tutorial or how to someone hase? Or just a bit of good explanation. Thx very much. Received on Wed May 07 2003 - 15:48:08 CDT
