Screen capture object from edit box

Hi, I'm trying to use the screen capture object to make a .jpg file of a small application I've built. What I need to do is use the text in an edit box ( limited to six numbers) to give the jpg file its name. The user types in a 6 digit number, clicks a button and the file is save to that name.
i.e. I'd type in 123456 , click a button and the file would be saved as 123456.jpg
Any help is appreciated.

What part of this process do you need help with?

Hi LB. I'm stuck with the "output" "set file name" part of the Screen Capture object. Is there a tutorial somewhere on it?
thanks

What do you mean you're stuck on it? You just take the filename from the edit box, right?
