Cannot redeclare class poll in.... C:\...

hey!

I've got a little problem with installing multiple polls on the same page... Sure, if it's the same poll type the stuff works like a charm, but here i wan't to display one poll type from demo_3.php for example and also a demo_1.php example in the same page. I tried to modify it by myself but i just can't get it. If someone solve this problem before, can you just put a link in here or try to help me out please?

I' get this if I include the demo_3.php example in the same page:

Fatal error: Cannot redeclare class poll in C:\dir_path\include\class_poll.php on line 10

This error returns the demo_1.php example poll

there must be two lines the same.

look for another line EXACTLY the same as line ten, comment using //
the one nearest the bottom of the page.
