Hi, I’m having some trouble with a Javascript code, and I was wondering if anyone can help:
I am trying to build a price estimator that has multiple fields. I would like the first two fields to have a price value based on a quantity price, so for example 1-10 qantity equals $30, 20-30 quantity equals $40 in the “Total” field). The rest of the fields in the following code work as intended whereas they just add based on the price to the right.

I had another idea that maybe I could get a set price with drop-down fields, here’s the code, can’t get that to work either, thanks!
