How do I Pass a Variable Through Bindable Functions?

Im trying to send my variable "notfroze" from my Script to my LocalScript but I get an error saying: Unknown global 'notfroze'

Bindable Function Name: "notfrozen"

Script Name: "IceShooter"

LocalScript Name: "IceShootScript"

The Bindable Functions Parent is the "IceShooter" script

Script:
getnotfrozen = game.ServerScriptService.IceShooter.notfrozen
	getnotfrozen.OnInvoke = function(notfroze)
				local notfroze = false
				wait(3)
				notfroze = true

LocalScript:
getnotfrozen = game.ServerScriptService.IceShooter.notfrozen
getnotfrozen:Invoke(notfroze)
print(notfroze)
