Script works in studio fine, but doesn't work in the regular game?

I have a regular script in StarterGui that checks each time the player respawns if they are on the prisoner team (Royal purple team). Then it fires a custom function called timer that starts a for loop to countdown the amount of seconds the player is in the prison before their team is changed back and they are respawned.

The script works perfectly in any testing I do in Studio, yet doesn't work in a regular game. I've tried several fixes and none of worked any help would be appreciated.

function timer()
	for i=120,0,-1 do
		if i == 1 then
			script.Parent.PrisonGUI.PrisonerFrame.TimeLabel.Text = "TIME REMAINING: "..i.." second"
			wait(1)
		elseif i == 0 then
			script.Parent.PrisonGUI.PrisonerFrame.TimeLabel.Text = "RESPAWNING"
			script.Parent.Parent.TeamColor = BrickColor.new("New Yeller")
			script.Parent.PrisonGUI.PrisonerFrame.Visible = false
			game.Players:FindFirstChild(script.Parent.Parent.Name):LoadCharacter()
		else
			script.Parent.PrisonGUI.PrisonerFrame.TimeLabel.Text = "TIME REMAINING: "..i.." seconds"
			script.Parent.Parent.TeamColor = BrickColor.new("Royal purple")
			wait(1)
		end
	end
end

if script.Parent.Parent.TeamColor == BrickColor.new("Royal purple") then
	script.Parent:WaitForChild("Menu").Frame.Visible = false
	script.Parent:WaitForChild("PrisonGUI").PrisonerFrame.Visible = true
	if script.Parent.PrisonGUI.PrisonerFrame.TimeLabel.Text == "TIME REMAINING:" or script.Parent.PrisonGUI.PrisonerFrame.TimeLabel.Text == "RESPAWNING" then
		timer()
	else
		print("hi")
	end
else
	--print("no")
end
