i sell gloves. to see my problem click gloves then pick one of the products.
The gloves are embroidered to order so the customer needs to tell me what to put on them. I have moved the product customisation up to the top but what i need is the customer to type in his information eg. lodge number and click add to cart without having to click the save button.

If at all possible i would like the field to appear below the size drop down.

eg.

£10.49
Quantity
1
Size
L
Lodge Number
xxxxxxxxxxxxxx

Add To Cart
but if that is not possible just to remove the save and make it work using add to cart button.
