Loading a URL as a variable for a button

I was actually able to figure it out thanks to some tutorials available at http://www.hello.to/fla which is a guy from Russia who's site really helped me out. Thank You!!

The solution was to set the button to
On (Release)
Get URL (variable name entered as an expression and not a string)

I am trying to load a URL as a variable and use it as a Get_URL action on a button.

I can load the variable into a text field, but how do I use it as a URL and assign it to a button????
