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
