Hi!

I’m trying to use values from Bubble input to make calculations inside the HTML element.

I tried using the ID Attribute.

I’m building an App that has a lot of complex calculation and the expression plugin isn’t suiting my need. So I’m planning in using Javascript to make the maths.

I’m open to suggestions too! 🤗

Thanks!
