[Cmpl] error (input/output): ... Input file 'production-mix-a.csv' not found

[Oscar Augusto Téllez Sánchez]

Good day,

I am new in Coliop but with a lot of energy. I am running examples but i cannot run the problem with .csv input file. The only reference i found is that the datafile should be in the same location as the program file. I tried but the problem persist.

any idea how to make it run?

thank you

Oscar
