Fatal error: Call to a member function?

[erbanfootwearInc]

I have added the "Must Select Attribute" contribution and all appears to be working fine until I get this error message:

 

" Fatal error: Call to a member function on a non-object in C:\Inetpub\wwwroot\erbanfootwear.com\includes\application_top.php on line 363 "

 

I get this when trying to Proceed to checkout. Line 363 is in CAPS and /// commented out for your convenience for your convenience.
