Checking 2 string variables

I am trying to make a text based horror game, but the code input doesn't equal the answer. Help!

     var codeinput : String = "";
     var curQuestion : String = "Welcome to the L.D.T.C Initiative. Do you want to begin?";
     var Answer = "";
     
     function OnGUI () {
         // Make a text field that modifies stringToEdit.
         codeinput = GUI.TextField (Rect (100, 200, 200, 25), codeinput, 25);
          
          if(GUI.Button(Rect(100,250,60,30),"enter")) {
               codeinput = Answer;
               //check to see if that varible = code.
          }
         
         GUI.Label (Rect (100, 75, 1000, 1000), curQuestion);
     }
     
     function Start () {
     
     }
     
     function Update () {
     
     if(curQuestion == "Welcome to the L.D.T.C Initiative. Do you want to begin?" && Answer == "yes"){
         curQuestion = "L.D.T.C Loaded. Would you like to learn more? Or continue?";
         if(curQuestion == "L.D.T.C Loaded. Would you like to learn more? Or continue?" && Answer == "learn more"){
             curQuestion = "the Long Distance Troop Control program is made to assure victory in any circumstance. Would you like to continue the operation?";
                 if(curQuestion == "the Long Distance Troop Control program is made to assure victory in any circumstance. Would you like to continue the operation??" && Answer == "no"){
                 curQuestion = "SYSTEM ERROR. CONTINUING OPERATION";
             
         }
     }
     
     }
     }
