I tested again with recordID 48 and postVariable at 5 for x large.
I do get one row with price.
Price gets added to cart.
However when set to -1 no price gets added to cart? Therefore customer cannot select option which should add specific price to cart.
I have no clue what has happen.
I've attached zip file hopefully you can scan over it and see what the problem is.
Thank you for all your help.
