Weapon shooting mechanism problem.

AWP, and other secondary weapons are not working. It seems that the code does not execute the line:

 playerShooter.Shoot(x);

I don't know why my whole function looks like this:

 public void PerformShoot()
     {
         if (Input.GetMouseButton(0))
         {
             if (playerShooter.primaryWeaponOn() ==  true && playerShooter.ammoCurrentInt > 0)
             {
                 switch (gameManager.GetComponent<GameManager>().primarySelected)
                 {
                     case "ak47":
                         playerShooter.Shoot(0.1f);
                         break;
                     case "m4a1":
                         playerShooter.Shoot(0.08f);
                         break;
                     case "scorpionvz":
                         playerShooter.Shoot(0.07f);
                         break;
                     case "ump45":
                         playerShooter.Shoot(0.11f);
                         break;
                 }
             }
         }
         else if (Input.GetMouseButtonDown(0))
         {
             if (playerShooter.ammoCurrentInt > 0 && playerShooter.primaryWeaponOn() == true)
             {
                 switch(gameManager.GetComponent<GameManager>().primarySelected)
                 {
                     case "awp":
                         playerShooter.Shoot(1.4f);
                         break;
                 }
             }
             else if (playerShooter.ammoCurrentIntSec > 0 && playerShooter.secondaryWeaponOn() == true)
             {
                 switch (gameManager.GetComponent<GameManager>().secondarySelected)
                 {
                     case "m1911a":
                         playerShooter.Shoot(0.15f);
                         break;
                     case "makarov":
                         playerShooter.Shoot(0.1f);
                         break;
                     case "pm40":
                         playerShooter.Shoot(0.21f);
                         break;
                 }
             }
         }
     }

Every variable is getting changed I checked it so it all should be good. I changed the code only in this class and the function is checking the variables in other classes which is another reason this should be working as I did not change anything in other classes. Some time ago this was working and now something happened.
