Hello Malinee,

it would be helpful, if you could supply an example that creates the error.

From what I have understood you want to write something like:

set P1;
set P2;
set P3;
set P4;
var x2{p1 in P1, p2 in P2, P3, P4 : p1 <> p2} >= 0;
minimize obj :
  sum{p1 in P1, p2 in P2, p3 in P3, p4 in P4 : p1 <>p2}x2[p1,p2,p3,p4];
solve;
# output excluding p1 == p2
for {p1 in P1, p2 in P2, p3 in P3, p4 in P4 : p1 <> p2} {
  printf "x2[%d,%d,%d,%d]=%f\n",
     p1, p2, p3, p4, x2[p1,p2,p3,p4];
}
data;
set P1 := 1,2,3;
set P2 := 1,2;
set P3 := 4,5;
set P4 := 6,7;
end;

Best regards
