Hi, I'm currently stuck on a problem that I can't figure out myself. I want the localscript to play a sound locally whenever a player enters the car. The script looks for when a child is added into the "DriveSeat" and detects whether it is a "Weld" or not. If it is a "Weld" then it should play a specific sound. All sounds are under the drive seat and the script is a localscript as I mentioned before. The car chassis is Inspare SS3. Anyway, here is the script I'm working with, it's fairly simple.
local carSeat = script.Parent
script.Parent.ChildAdded:connect(function(child)
if child:IsA("Weld") then
carSeat.Startup:Play()
wait(1)
carSeat.Chime:Play()
end

Two problems with your script: 1 On line 4 use Connect instead of connect since it is deprecated. 2 You never ended your ChildAdded event. Add a line and type "end)"
Hmm, still doesn't work I've done everything you said to do.
