What is C(i, j) on line 60 and 63? It is never defined in the code and being used in the if condition.

Hope this helps.

Error 141 is because of the error I mentioned. If you fix the issue with parameter c(i, j) by providing values, your model will be solved (clearly enough, it cannot be solved at the moment as GAMS does not know C). If you click on the text below error 141, .lst file will open and show you exactly which element is causing it.

If you see that, you will realize the error is coming from two places. First is C(i,j) and second is " display z.l, x.l;". This makes perfect sense because if the model is not solved, there won’t be any .l(level) values to show.

Therefore, it is very important to first fix the error with C(i,j)
Hope this helps.

Please note that C(i, u) is not defined anywhere in the code you have attached.
