Thanks, Kevin-

I never realized you could specify the type of variable in php - I 
thought $foo could be a string or a number.

Does it cause problems that I was trying to use a session variable?

Even though I have my original problem resolved (thanks to a fx.php 
upgrade) I'm still interested.


How can I convert the type to a number?
