Goto isnt working within a IF statement but other lines are working

Question

 if NumberOfIncorrectLetters = 13 Then
                            GraphicsWindow.PenColor="white"
                            HangmanPart13 =  Shapes.AddRectangle(40,5)
                            Shapes.Move(HangmanPart13,1133,575)
                            GraphicsWindow.DrawBoundText(1000,900,500,"You Lost, the word was : " + WordYouNeedToGuess)                       
                      
                            NumberOfIncorrectLetters = 0
                          
                            Goto Start

This is the IF statement, the other lines work but I can't use goto to restart my hangman game. I want to run the script from a point just below the top but dont know any other ways.
