1. Try putting it quotes, single or double.

2. Where are you putting this qstring=A? Typically a "qstring=x" is
specified in the URL and passed to mapserver. And then your map file
would have a FILTER and FILTERITEM for that layer.

3. Remeber that you're working with regex expressions, not SQL statements.
