JS Errors with DA Page Creation

I've been attempting to work with the Data Assist Page creation feature to create backend admin pages and have been running into various JavaScript execution errors part way through the execution process and the process halts. I've attached two different errors that were encountered. The first was encountered when creating a set of pages from scratch and happened after the insert page had been successfully completed but while the results page was in progress. The insert page would function correctly when tested in terms of adding records but the results page was incomplete due to the halt.

The second was encountered attempting to create the User Admin (including creation of the DB tables) after the insert page and update page had been created and while the results page was in progress. The DB tables were successfully created but only the two pages produced.

I've been able to get pages to run through succesfully so long as the fields are simple and a direct reflection of what's in the tables...the moment I start trying to use menus/lists that point to other tables for values/names, errors occur.

I'm running DW CS5.5, Windows 7, and have the DataBridge, DesignExtender, and eCart extensions installed as the latest versions. I tried uninstalling the Databridge extension and reinstalling and the errors persist.

I'm not sure if it is related, but the pages that do execute when the errors are encountered have HTML and PHP code irregularities at the end of the pages in terms of the final html and php tags getting jumbled together and repeated incorrectly. Those are easily fixed by hand, I include it here only as a possible additional symptom. Those jumble errors don't occur when I try to create simple pages and the code is clean and works without issue.
