Error in Equation
What is the reason for this error? obj_location.. f_location =E= sum((r,c), w(c)*d(r,c)*a_rc(r,c)); **** $171,171 Domain violation for set. Sets c /c1*c3/ r /r1*r4/ i /i1*i4/ j /j1*j4/ k /k1*k3/ s /s1*s3/ N /c1*c3,r1*r4/; ...

Error 195,318,409
Hi, I can't understand these codes are for:
C(k) physical space required by vehicles k
/ k1 50, k2 75, k3 100/
$195,318,409
*The Sets of k is k1*k3
C(k) physical space required by vehicles k
/ k1 50, k2 75, k3 100/
