Hi,
I am looking to create a custom calculator for my store on some product pages.
It will be similar to the one seen on this page
https://www.2hraquarist.com/en-au/products/2hr-aquarist-apt-sky
If you scroll down, you can see that the user can enter their target ‘Gh’ and current ‘Gh’. I can provide the maths, but need help installing the calculator.
Thanks!
