    I appreciate if any one can verify it for me since I get errors! 

    dvar boolean x[i in A][s in S];

    dexpr boolean y[i in A][s in S][w in W]=i%7==w ? x[i][s];

    By this expression I am trying to condition on values y can get for each day of a week based on the values that x have for any day!

     

    I appreciate your comments,

    Hi

    can you try with dexpr int and with parenthesis ?

    dexpr int y[i in A][s in S][w in W]=(i%7==w)?x[i][s]:0;
