Hello,
I am trying to use a solve block to find values for two variables but am running into difficulties. It seems that I am always getting an error "variable is undefined". After searching the forum it seems this is the standard error from a solve block and doesn't really give any clue as to what I'm doing wrong.
I originally suspected that I was having issues since I was making use of functions with conditional statements, but after experimenting and removing the statements I am still not getting any results. Manually, I can come close to getting a solution.
Please see attached sheet. Thanks.
