How do i fix this script? (Audio)

To find a random a random child, you would use the GetChildren() function.

Here is an example on you could use this:

while true do
local song = script:GetChildren()[math.random(1,4)]
if song.ClassName=="Sound" then-- Just to make sure it's an audio/sound instance
song:play()
end
wait(2)
end

GetChildren() returns a table of all of the children in a specific instance.

I hope this helped you with your problem!

YOU CAN ALSO USE AN ALTERNATIVE WAY! You can use ToString() since the Name Property is a string value. Tostring() converts numbers to string values. To use this alternative way, you must have the sounds numbered as numbers.

while true do
local song = script:findFirstChild(tostring(math.random(1,4)))
song:play()
wait(2)
end
