Why will this not change this image button image id?

openStatus = false

if script.Parent.Parent.Parent.Parent.Parent.PlayerGUI.DialogSettingVisible.Value == true then
    script.Parent.Chosen.Image = "rbxgameasset://".. 4309789542
else
    script.Parent.Chosen.Image = "rbxgameasset://".. 4309787002
end

if openStatus == false then
openStatus = true
else
openStatus = false
end

This will not change the id, why is that?

Thank you
