I have this code:

{string} Users=...;
{string} Subcarriers=...;
int CostUsersSubcarriers=...;
int DemandUsers=...;
int Subc_BR=...;

dvar boolean AssignUsersSubcarriers;

maximize
sum(i in Users)
ln(Demand[i])*Subc_BR;

subject to{

forall(j in Subcarriers)
ctAssignment1:
sum(i in Users)
Assign[i][j]<= 1;

forall(i in Users)
ctAssignment2:
sum(j in Subcarriers)
Assign[i][j]>=1;

forall(i in Users)
ctDemand:
sum(j in Subcarriers)
Assign[i][j]*Cost[i][j]>=Demand[i];

}

And the date file is this:
Users = { "user1", "user2", "user3", "user4", "user5" ,
"user6", "user7", "user8", "user9", "user10" ,
"user11", "user12", "user13", "user14", "user15" ,

My problem is that the subcarriers which not used are assigned to the last user of my array in solutions tab.I want those subcarriers in the decision variable array to be 0(that are not used).What constraint i have to write to achieve this?
