New product entered - 'add to cart' not functional

[ChrisB257]

Have added a new product but 'add to cart' does not work properly - shows all zeros. All other store items successfully register in cart and transactions function fine. (Using Ajax cart successfully for default theme.)

The new item has three combinations, like some other items, each set up with appropriate pricing data. Thus far cannot find any settings that would prevent the 'add to cart' success - result is same even if qty change from 1 to 2 or 3 - cart is not seeing it with relevant figures.

Attached - image of the item page - looks normal. Plus supposed success 'added to cart' grab - all zeros?!

Any thoughts from the gurus as to what might have been wrong in set up?? Puzzled right now.
