I'm trying to calculate this form with quantities and addition, some fields have required amounts and the other fields are quantities and amounts for input. I am trying to add all of this together and apply tax. Any help would be much appreciated. Here is a link of the Excel spreadsheet I'm working from:
Estimator Form
Here is the code of what I have so far:
