Hi Jason,
Did what you said and replicated the page and copied the freshly generated cart code over the existing cart code and it worked a treat so it resolved the issue.
The thing I need it to do is just add a singe charge of $7 to an item that meets the criteria, or $3.89 that meets the alternative criteria no matter how many of that item is in the basket, so for instance the item that meets the criteria for a $7 premium costs 1$, then this would show as $8 ($1 cost + $7 charge) Now if there was 3 of that item it should show in the basket as $10 ($3 dollars for the 3 $1 items and a charge of $7)
Almost there now.
Can you help?
Thanks
Paul
