Dear Rev Proframmers
I need a simple stack to do this.
I want a text field to enter amount of savings, interest, and it will put out in the label Princ, Interest, & total.
I was told the above formulas is needed but math is not my thing.
I used an existing stack for testing, so I used items of a field for input rather than separate fields. But allowing for that, it should be clear
put item 1 of tVar into P put item 2 of tVar into r put item 3 of tVar into m put item 4 of tVar into t put P * ( (1+r/m) ^ (m*t)) into field "lockedField"
(Remember that for a 4% interest rate, the value you should use here is "0.04", not "4".
Took me more tries than I'd like to admit to realize that myself :-)
