after add to cart

So i got my other issues figured out. Now when you click on the add to cart button it goes to a blank page. Now is that because I dont have autherize.net not hooked up yet or should it do something else. I don not have any payment moduels hooked up yet.

Thanks for the help on this one.

Search the tutorials link above for blank page

after i looked at the error log this is my first item

[30-Jul-2010 13:23:10] PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent (output started at /home/content/l/u/c/lucylu022/html/huggle/rebuild/zencart/index.php:8) in /home/content/l/u/c/lucylu022/html/huggle/rebuild/zencart/includes/functions/sessions.php on line 110

this is what line 110 looks like

$temp = session_start();

i know something needs to be in the bracket any ideas there

Look to what spawned the error
