Elle here from Shopify's Social Care team.
Instead of simply having a 'back' button, I would recommend using breadcrumb navigation here so your customer can easily revert to the previous pages they've visited.
In order to accomplish this, you can follow this guide here.
If you'd like assistance with this customization, just let me know and I can have our theme support team do the customization for you as you're using a Shopify Theme! You can read more about the design time that comes with using one of our themes here.
Hope this is helpful!
Thanks for the input here
I am using Gempages for my design, although I was able to do it on my Debut theme clone on shopify, and it worked perfectly. Unfortunatley all I can design is my header and footer
With gem pages I am trying to figure out how to implement the code there, waiting for response from their support.
Again thanks for the input
