Welcome to the Shopify community!
and Thanks for your Good question.
you can put the code product template > product template section > find text add to cart or just cart
you have add this code above this add to cart button
Hi, Thanks so much for your reply. I'm new at this so I have some more questions if that is ok?
I can't find the cart text - will it be in the top multi-coloured section?
Also, do I have to duplicate and create a customized product section, or just put it in the one that is already there?
Thanks for details
if you need more customization can you please contact to PM
