JS or PHP (a little OT)

hello: I have created a form that spawns a child window where user makes a selection and value selected in child window is returned to parent form textbox. This works great! (thanks to those who sent replies, it was just a syntax error...getting friendly with the netscape javascript console!) Problem: I have 6 textboxes on the parent form and want the child window to keep putting values in the parent form textboxes, but only if they are empty...for instance: user makes a selection in child window and clicks button to put value on to parent form textbox 1...user wants to put another value, clicks button on child form and script checks parent form, sees that textbox 1 is full so puts the value into textbox 2, and so on... Question is...can this be done in javascript or do I need to go into PHP? Thanks Luis __________________________________________________ Do You Yahoo!? Yahoo! Messenger - Talk while you surf!
