add to cart multiples of 2

Hey Ray

Am trying to get the cart working on that site we discussed the other night - the one where I have a matrix of products and needed to set it up so they could add other items that didnt fall into the matrix.

Have got the 2nd table set up and the backend working fine.

I have the add to cart on the front end 'working' with a couple of probs.

If you add an item to cart on the book-now.php (http://goo.gl/DbREYH) page you then get taken to cart.php - so far so good

Now that you're on the cart.php page, if you add the top item to cart (http://prntscr.com/bmmyps) for some reason it adds 2 items (and multiples of 2 every time you add to cart) to the cart for that line.....

Problem 2.

Clear the cart on the above page. You should still be on cart.php but the original matrix is showing. Add an item to cart there it is adding the item in multiples of 2 and no product name (http://prntscr.com/bmmzz4) - not sure whats happening there - and if you then try to add the extra item (http://prntscr.com/bmn0f2) it adds it (with the product name but again adds in quantities of multiples of 2......

have attached the cart.php and book-now.php pages if it helps

Thanks

Jamie
