why i'm getting the error "attempt to index nil with "set""?
The error happens in the _G.Vehicle Health, i also have another command that is is connected to this script its on the bottom
local hum = tie:FindFirstChild'Humanoid'
if hum and hum.Health/hum.MaxHealth <= .4 then
script.Alarm.Volume = 1
else
script.Alarm.Volume = 0
end
_G.VehicleHealth.Set(hum.Health/hum.MaxHealth)
end)
the script on the StarterGui
function _G.VehicleHealth.Set(n)
script.Parent.Parent.Visible = true
ChangeHealth(n,1)
end

You mention that the script setting the variable is in StarterGui, so it must be a LocalScript (If it isn't, then it isn't running so the variable wouldn't get set anyway).
I also am assuming that first script is not a LocalScript, and so _G.VehicleHealth.Set doesn't exist yet on the server. The _G table is shared only between scripts in the same context level, so the server does not have access to the same _G table as the client (And therefore errors when you try to index it with non-existent keys). To fix this you need to be setting the function in _G in the same context level as where you're calling it.
