Hello, I would like some help making a calculator for the Age of Ishtaria Wikia ( ). I want to allow the users to give some input value and then use those values to give several final damage outputs.
This calculator from the Runescape Wikia ( ) looks like what I am looking for, but it seems to use Javascript and I don't know how to utilize that and I don't know who or where to ask for who made that calculator.
