Well, that one comes and goes... the one that is persistent is

"Warning: Cannot use a scalar value as an array in ../view_cart.php  
on line 43"

I've found other sites that seem to have had this error at one time  
(Google shows them), but in most cases, they apparently fixed the error.

Has anyone else had this one? How did you solve it?

I did; all the session stuff is at the very top of the page. I also  
did as you suggested and re-examined my include files; the thing is,  
these errors are showing up not just at the top of the page, but also  
in the middle of a page where the page should be showing a list of  
items in their shopping cart (so it's a piece of looping code using  
"foreach").

Thanks,

Bob
