Big Given-Find Solve block: all is good, but still 'variable is undefined'?

[ptc-4693125]

Hi!

I've written a large Given/find Solve block, and read previous answers to questions like this where intermediate steps were incorrect. Each of my intermediate steps solves fine, but the final Find() statement still throws the "This variable is undefined." error!

Would some kind soul possibly look at my sheet (attached) and see if they can find the problem?

Thank you!

Make appropriate parameters explicit functions of the variable you are trying to find. lt's also a good idea to keep your assignments and function definitions outside the Given - Find block - otherwise it's too easy to get confused. See attached.

Thank you very much Alan.
