Does anyone know how I can edit this part of the store when I click on the red Add to Cart button? https://www.badzachx.com/merch

I dont want that purple button etc, where do I edit this section?

Hi Sam,
You can only edit visually the elements at the product page.
Go to the product page’s settings button.

For further questions, please contact support@wix.com.

Have a nice day and best of luck!

I have done this time and time again but the button is still purple even though the settings show it as red.
