while wait() do
if game.Players.NumPlayers > 1 then
    if InterP.Frame.List.MapTitle.Text == 15 then

    else
        InterP.Frame.List.MapTitle.Text = 15
    end
    if MoreThan1Plr.Visible == true then
        MoreThan1Plr.Visible = false
    end
    InterP.Visible = true
    for i = 15, 0, -1 do
        InterP.Frame.List.MapTitle.Text = i
        wait(1)
    end
    RandomMap.Visible = true
    wait(2)
else
    if MoreThan1Plr.Visible == false then -- Output error?
    MoreThan1Plr.Visible = true
    end
end 
end

This may be because of the scope. Check that "MoreThan1Plr.Visible" has a value

print(MoreThan1Plr.Visible)

Change "MoreThan1Plr" to a global variable
