I'm learnig to use AMPL to solve some linear programing related problems; but i have a syntax error with a part of my code, and i dont know how to solve it.

But when i run the mod file, i have this error
Taller1.mod, line 36 (offset 981):
syntax error

I checked my code, but I don't understand what the error is. Please! Help me.
