If you take a look at my website at http://www.undergrounds.com/listing.php3?listing=A , you will see that a blank page is returned with no errors.
However on http://www.undergrounds.com/listing.php3?listing=F , which is the same PHP page with a different variable passed, it works fine. http://www.undergrounds.com/listing.php3?listing=T also works, as does http://www.undergrounds.com/listing.php3?listing=Y . But none of the others.
I have reduced the problem to the query line. (when I remove it the page works, but errors are generated because there is no database access)
Any ideas why certain variables work and others don;t?
