Odd Solve Loop Bug

[KevinHardin]

I am kind of new to MathCAD but I seem to be having a strange bug. I have a simple solve loop that works in one sheet. When I copy it to a new sheet I get the error "This variable is undefined". I can't seem to find any reason why it will work in the current sheet but won't in another one.

I attached the working copy. Can anyone else copy the entire loop into a new worksheet and have it still work?

Thanks in advanced.

If you look on the original worksheet under Tools/Worksheet Options.../Calculation you will see that the 0/0=0 box is checked. When you copy to a new sheet, the default is that the 0/0=0 box is unchecked. So, at some point in the calculation a 0/0 occurs.

To avoid the problem you can either check the 0/0=0 box in the copy sheet, or simply replace the initial guess by 2 (which doesn't seem to incur a 0/0 problem).
