I don't think that's going to work as a URL. What I would suggest (note, I'm working with VERY limited experience here), is that you have the query built in to the page the link is going to, and just pass the variable bits via URL.
Ie: <a href="../mainlist2.php?value=variablePassedFromPage">2001 Session Progress</A>
And the query on the page would read something like ...
mysql_query("SELECT field1 FROM table WHERE field2 = '$value'");
I may be missing the subject altogether though.
