I am trying to create a ROI (return on investment) calculation PDF. I have a numeric field that I want to have increase or decrease by value X when I press an "up" or "down" button. I can't figure out how to connect a button to a numeric field where it dynamically changes its value.
I'd like to use 4 sets of these variable where the numeric fields will effect other fields below which will be auto calculated.
When this form is created I then want to to work on an iPad.
In Excel I can do this using Spin Buttons - and on an iPad using Numbers you can do this using a Stepper.
