The Tale of 2 Servers

Server A:
Master SWF
Calls form.swf on Server B.

Server B:
contains form.swf and is pointing to a processing file on Server B.

When I run form.swf on Server B everything runs fine …its awesome.

When I run the Master SWF from server A, it loads up the form.swf from B, I input information into its field, and click submit.

When I check my db viewer on B, the information was not sent.

Any thoughts, theories - etc? The mailing list software is ran on Server B. The website on A.

Thank you.
