Hi Balai, thanks for the reply. The customer adds a coat to the cart, the custom fields are things like the colour of the coat, the colour of the lining, reflective strips etc. The last thing they offer on some is for the embroidery which requires the customer to enter the name (max 10 letters) and select the number of letters from a dropdown (so the price is added) minimum £5 up to £10 in £1 increments. This is done with Custom Fields at the moment, do you think the product builder would be better? A lot of their customers are older people who are not great with computers so I want to make it as easy as I can.
