Help with iterative calculation

[dabs230]

Hi,

I need help. I need to perform an iterative calculation to obtain a value automatically.
I leave the mathcad file to for help me. The problem is at the end of the file.
Thank you.

Looks like you're trying to do a solve block, with the "given" but I see no "find"

Yes, beacause I delate the "find" because not working.
I don´t know if this method is valid to solve my problem

Perhaps you should start with a smaller problem and work your way up

This problem is now smaller. The real case is more long and dificult

You cannot send undefined variables through a solve block.
