I need help in adding plus/minus quantity selector buttons to my Shopify site Debut Theme. I already downloaded an app (Extendons Quality Selector), which produced what I was looking for; however, the plus minus buttons weren’t clickable (the quantity didn’t change when I clicked on them). Also, I edited the code using some advice online; however, that didn’t work either.
If anyone could assist me in fixing this issue, I would greatly appreciate it!
Hey! It sounds like the app may not be properly connected to your theme’s cart logic, especially since Debut is a bit older and may require manual integration. I’d recommend checking if the app’s JavaScript is being blocked or conflicting with other scripts.
If you’d like, I can help take a quick look at your code and make sure the plus/minus buttons are correctly updating the quantity input and syncing with the cart. Let me know happy to assist!
Hi @djlangen 
this is an advanced theme customization beyond the scope of the forums.
If you must DIY something like this SEARCH first it’s a literal rule in the guidelines to respect others time and yours to use what already exists.
