Can you please take a look at the following piece of code and help me understand why I am getting the error below and how to fix it?

{int} Q1=...;

{float} q[CmRange]=...;

  
 dexpr float SVM = Q1* q[j]

Error:

Operator not available for {float} * {int}

Hi,

you mix sets and scalar values.

Let me fix the objective to help you undestand.

dexpr float SVM = 
 first(Q1)*(sum(j in CommunitiesRange, i in CandidateSitesRange)first(q[j])*n[j]*d[j][i]) 
 + first(Q2)*(sum(j in CommunitiesRange, i in CandidateSitesRange)first(l[i])*first(f[j])*n[j]*d[j][i]);

would work fine.

Q1 is a set. You can use an element of a set in an equation but not the set itself

regards

Thank you so much Alex!
