Errors are appearing but i don't know how to fix these...

Im getting 3 errors from this script

void Update () { playerVelocity.x = Input.GetAxis("Horizontal") * WalkingSpeed;

   if(Input.GetKeyDown(KeyCode.right))
   {
       playerVelocity.y = JumpingSpeed;
   }
   else
   {
       playerVelocity.y = rigidbody.velocity.y;
   }

Here are the three errors

Assets/Scripts/PlayerScripts/PlayerController2D.cs(27,39): error CS0117: `UnityEngine.KeyCode' does not contain a definition for `right'

Assets/Scripts/PlayerScripts/PlayerController2D.cs(27,20): error CS1502: The best overloaded method match for UnityEngine.Input.GetKeyDown(string)' has some invalid arguments Assets/Scripts/PlayerScripts/PlayerController2D.cs(27,20): error CS1503: Argument #1' cannot convert object' expression to type string'

Any help is appreciated and merry christmas
