Change Input Text Var w/ ActionScript?

Greetings Kirupians,

I have a cart system I designed, in the check out process the user fills out their billing info and are given the option to check a box if the shipping info is the same.

I would like to have an event listener which looks for the box being checked and at which point changes the var’s on the input texts for shipping to the ones used in billing info. So in essence checking the box will populate the shipping info fields.

Any suggestions here?

Thanks in advance!
