Script:
while true do PBL = workspace.Sound.PlaybackLoudness if PBL + 100 then game.Workspace.BlueAndRed.BrickColor = BrickColor,Blue() if PBL + 600 then game.Workspace.BlueAndRed.BrickColor = BrickColor.Red()
end
For some reason it says:
Workspace.BlueAndRed.Script:7: 'end' expected (to close 'if' at line 3) near '< e o f >'

You must close the "if" statements with "end"
if; then; statements always need an "end" at the end of the statements. ALWAYS.
