CPLEX OPL ERROR RUNTIME : not to type lloType ,

Question

It is confusing; I do not what the problem is. Does anyone know what the problem is?I get this error,"opl not to type runtime error", for some expression in my objective function when I am running the code in CPLEX.i'm working on a thesis with a scheduling problem design so that it's suitable for A2 is deadhead trip, I'm getting an error that i can't output the result with string, please help me review the code, I'll be very grateful My code is as follow:

`int numLocomotive=...;
range RangeLocomotive=1..numLocomotive;
{string} Pij=...;
{string} Node=...;
{string} Locomotive=...;{string} Vd=...;

{string} Vs=...;
{string} Vf=...;
{string} Exp= Va union Vs;
{string} Exp= Va union Vs;
{string} Exp= Va union Vs;
{string} V= Vd union Va union Vs;
int ckm=...;
int cloc=...;
tuple A{
string I;
string j;
}
  {A} A2 ={<i,j> | ordered i,j in Node};
  int dis=...;
  dvar boolean x[<i,j> in A2];
  dvar boolean s[Locomotive];
 dvar boolean q[Node][Locomotive];


  execute PRE_SETUP
 {
  cplex.epgap = 0.001;
  cplex.tilim = 21600;
  }

  dexpr float Totalcost = sum(<i,j> in A2)(dis*x[<i,j>])*ckm + sum(k in Locomotive)s[k]*cloc;
  minimize Totalcost;

  subject to{
