I have following equation to model in CPLEX

But i am encountering problems with the sum within the sum. In CPLEX i got the following code:

forall(k in Rn,t in T) ctNightCapacity[k][t]:
        sum(p in P:k==b[p] && t>=alpha[p])
          1-sum(t in T: E[PHI[p]]<=t<=minl(t,L[PHI[p]]))x[PHI[p]][t]<=RN[k][t];

But i get an error that p is not defined. Can someone help me here? I couldn't find any solutions on the web or the IBM manual.

Thank you in advance!

Hi

do not hesitate to attach .mod and .dat so that other users could try
