stop script stretching text on click

Site URL: https://raspberry-garlic-8h62.squarespace.com/

Hi everyone, 

I am testing a script to see if i can implement on squarespace  - but I need it to stop stretching on click.  I'm a beginner at JS and cant figure out how to make the action stop when you click.   Any help would be greatly appreciated!

Site PW: stretch 

Here's the JS 

// stretch text 

var originalWidth = $("h1").width()
var originalHeight = $("h1").height()

$(document).on("mousemove", function (event){
	
	var scaleX = event.pageX / originalWidth
	var scaleY = event.pageY / originalHeight
	
	$("h1").css("transform","scale("+ scaleX +","+ scaleY +")")
	
})

Hey @creedon Thanks so much! I was forgetting the semicolon! ROOKIE mistake. Works perfectly 😊
