Can't access xml file from swf

I have a curious problem.

I have an swf file that is trying to read an xml file from this server:

The full Url looks like this: Search&w=google&w=yahoo&w=youtube&w=msn

Now by, itself, the swf reads the xml file w/ no problem. It also reads the xml file fine if it’s embedded in an html file and lives in the appropriate folder
in my website directory. The problem is when I embed the file in the actual page of the program.

I have the security settings as such:

import flash.Security;"");"");"");"");

I also have the crossdomain.xml set as such:

  <allow-access-from domain="" />
  <allow-access-from domain="" />

Is there anything I’m missing here?
