I have been trying to get an answer on this for a week in support but not having any luck as my questions are being ignored. I am trying to use a custom button on the signup form because the grey original button does not convert well and a css button color change is not going to cut it either. Therefore, I need to remove the original button and use the custom button built in the shopping cart section. I also need one for each product, as each product has it's own specific button. Can anyone give me any tips to get rid of this default button?
