Hi

You need to learn proper syntax and how to code in mql4. It should look like this to work.

       int first=20;
   int second=25;
   int third=30;
   int end= (first+second+third);
   //--------------------------------------
  switch(end){
     case 75:
       if(first ==21)
        {Print("first is 21");}
       else if(first == 20)
        {Print("first is 20");}
       else
        {Print("case 1: first is something other than 20&21");}
        break;
             
     case 23:
       Print("case 2");
       break;
     case 10:
       Print("case 3");
       break;
     default:
       Print("no case");
       break;
       
    }
  ExpertRemove();

Have a nice day👍📊
