When I input Amazon List ID as a user, I am getting the following error when I try to return to the profile:

Fatal error: Call to a member function getText() on a non-object in /home/newlifen/public_html/components/com_comprofiler/plugin/user/plug_cbawslisttab/awslist.php on line 112

Line 112: $ProductPage = $xmlDoc->getElementsByPath('/ListLookupResponse/Lists/Request/ListLookupRequest/ProductPage'->item(0)->getText();

I am probably entering the wrong information into the field, but I am unsure of what to enter. What is the "Amazon List ID" - is it my email? I don't see any other references at amazon.com.

Please advise. Thank you!
