I'm a beginner with action script and i need to make a project for a friend...

I need to make a presentation in flash and after everything is finished i have a button that should open a link.

Now my issue is that the programmer asked me to make the flash read the link (that should be open on click) from a html file, because that link will be changed from time to time ... is that possible?
I'm using action script 2 trough the animation.

Thank you very much!
