HTTP 500 with .php page

[rickymay]

I have a small educational php site at www.rickymay.com/teach.
the index(login) page successfully passes me to a second page of listed options (http://www.rickymay.com/teach/teachclass.php), but moving to a third page of those option details (http://www.rickymay.com/teach/teachass.php?classnametime=Extensive Reading (Th 10-12)) gives me an HTTP 500 "website cannot display the page" error.
As you can see, I use the GET METHOD and use blank spaces in the URL linking to that "third" page, so is that my problem? Or is it the temp directory that needs to be changed on the php.ini file (that I've read about at this forums); if so, where is the php.ini file? I know where it is on my computer, but I don't know how to find it in my root folders at discountasp.net.
Thanks for anything,

Thing is, everything works perfectly on my testing server. I upload to remote server and I get the error.
I fear that I've not asked a very clear question, but hope to hear from anyone who might have suggestion.

I'm afraid you won't have access to the php.ini file, however, I've tested your site, and everything seems to be working correctly. I'm not seeing any HTTP 500 errors.
