Need help with XML menu in flash

I am developing a xml back-end menu in flash however I cannot figure out how I can set behaviors to my buttons. For example when a button is clicked, I want one button to load in an external SWF, JPG, or PNG. Another button to get URL within the same browser window, another button to open up a new broswer window and lastly another button to open up a new pixel specific sized window. I uploaded my in progress files at . Click on all the buttons and you will see all the specific questions there. For you Flash Actionscript expert should be a breeze. :wink:

There is the XML file and the FLA. Please help!! Thank you in advance!!
