Hi Ben!

Thanks for your help and for SelectQuery! Slowly I learn. It's working 
now with the page variables. Thanks to SelectQuery I will finally be 
able to put my friend's database on my site. The SELECT command looks 
kind of like a Pandora's box tho.

MONTH() and DAYOFMONTH() don't work for me. Could it be the version of 
MySQL that I have? I know nothing, of course.
