How to make a image label change when a bool value is false?

So I'm trying to make it where when the bool value is false it changes the image of an image label but it doesn't work.

local imagelabel = script.Parent.Parent.Bulbasaur     
local part = workspace.Bulbasaur                                
                                                                                     
if part.Value == false then
	imagelabel.Image = "rbxassetid://1179108570"
end
