Thanks for the heads up :) I had printed out the $sqlst and it printed out with the $AuthUser variable included, but it's bizarre... I installed DBI and the DBD modules and whenever I try and run a script it always comes back with the "incomplete http headers" so then I try something different and nothing prints out, no error messages, etc.
I'm on a 2003 server box and if someone could post the proper DBI connect statements with variables (even an example) to MS SQL and a basic select statement I could take it from there.
