Generating 508 compliant output for access via SharePoint

In order to make our WebHelp application accessible via a Sharepoint folder, our team lead was able to move all output files (from the ISSL/WebHelp folder) to a single folder then move the files from the resource, whdata, whgdata and whxdata folders to the same [new] location so that all files associated with the RoboHelp WebHelp project are in the same area.  Next, he edited the whproj.xml file and changed the datapath from "whxdata" to " " (null). This works fine for primary layout output that isn't 508 compliant, so I duplicated the same steps after generating 508 compliant output to see if I'd get the same results.  After moving all files to a single folder and uploading to a test server (not Sharepoint), the table of contents page [frame] "can't be found".  I know that the toc tag in the whtoc.xml file has a root attribute that points to "whtdata0.xml".  This file is in the same folder as everything else.  So why does it not show the TOC?

Thanks,
