I am still stuck. I ahve provided the entrie code below. My last issues is that I want to change the refence to "Output1" and "Output2" after each pass through the calculator, so that the anser are written to O2

2, the O3

3, then O4

4, and so on.
Thansk to your help, I am close, but not quite there.
