Can anyone help me . there is CPLEX Error 1217: No solution exists. Problem is integer infeasible. Couldnt find solution. You can change number in table . I just need an answer. Thx for helping

Re: CPLEX Error 1217: No solution exists. Problem is integer infeasible.
Please use the code tags as mentioned in the rules. Otherwise your table formatting is broken and the code can't be executed without errors.

Re: CPLEX Error 1217: No solution exists. Problem is integer infeasible.
This is the result after click run. This is my homework idk how to use it properly and cant see any error excep error 1217. Can u help me you can change the numbers there is no queestion I create one and I can change numbers,lines, operaters etc.
