comobBox with URL's...from an external file

I am trying to populate a comboBox in Flash MX with URLs.

This is no problem, but I want to use an .as or .xml file to load the URL's in the box and activate them, NOT from the editor window, which is slow and cumbersome to use.

I can populate the comboBox externally as I want, but it doesn't work when I click on them......

Can anyone help me with this...........???


Thanks in Advance.......!
