I have submitted a ticket, along with all the files in a zipped folder.
Initially, the problem seems to be set in motion because the record sets have lost the definition of their connections. Redefining the connection resolved the first two queries, but left others with undefined variables. Dreamweaver won't restore the connection until the undefined variables are addressed and I don't know what their run-time values were supposed to be.
It almost seems like the product is hard-wired to be in one and only one folder, which would be a really short-sighted way to write the code because of issues like testing server verses production server.
