Thanks!

Hi Christopher



In your equation, you sum over Shift, Language and Period on the LHS. On the right hand side you have req(Language, Period), but how should Gams know which req to take (for which pair of Language and Period)? You should have something like



…. =g= sum((language, period), req(language, period)); to make sense.



Cheers

Renger
