Patrick and All, I figured out my original error. In my XML file I was trying to use a variable without including it in the line:
<make>ACK.Text_Sanitize($msg)</make> the $msg is what I added and that error no longer occurs. This error: RuntimeError: attempt to set_msg_handler() on bad input message port! still occurs, but that's just going to take some time for me to learn about PMTs and PDUs. Thanks for everyone's help!
