Use textbox to control printing

[Jonathan]

I have a question for everyone, what syntax would I use
to control printing. For example, I want to use a Yes/No
Button on a form that would give me 0/-1 as a result.
Would there be a syntax I could use to print only with a -
1 result using the print syntax through a button..?
perhaps some kind of if statement saying if value=-1,
then print else don't print.

thanks
