I'm trying to get to grips with Flash Builder 4.5 and have been struggling with this problem for a week now, if anyone has some suggestions I would really appreciate it.

I have been looking for a way to pass a string variable to HTTPMultiService for the baseURL path.

I want to pass the test.text field contents to the HTTPMultiService for the baseURL to be the base path but i just get an error.

Is there a way to pass a variable to the base url to be used as the base path?

My code is as follows.

<?xml version="1.0" encoding="utf-8"?>
