Looking for some help. When I use this code to add to a shopping cart, the first item goes fine, but when I go to add a second and third, the first one and the second disappear. I am puzzled. Any body got a suggestion

I don't notice anything immediately that would cause the issue you describe.

But you'd need to nail down whether the cart array is actually getting cleared, or whether it's just that your display code doesn't show the entire cart for some reason.

The best way to do that would be to add a
Code: 
   <CFDUMP var=&quot;#session.auth#&quot;>
right after the line that does the ArrayAppend():
Code: 
   <CFSET ArrayAppend(session.auth,strTempItem)>

This will give you a dump of what's actually in the cart after you add an item. If the cart array is being appended to properly, and all items are actually getting added, then that means somethings just wrong with your cart display (one or more of your CFIF conditions are not being evaluated properly). If the array is getting reset, then something is definitely amiss with the appending code.

Thanks carl, I actually figured it out, I adjusted the session variables on the server and that fixed it, I didn't know that the server had to be restarted to have the settings take effect
