Cant get script to play 2 different sounds

[micheal1230]

When you press 'n' you get a siren sound, but when you press 'n' again you get a different siren sound but the second sound wont play!

local sounds = { } 
  
-- Bind Keys required

    bindKey("n", "down", toggleSirens) 
     
    for key, value in ipairs(getElementsByType("vehicle")) do

                attachElements( sounds[value], value ) 
                setSoundVolume(sounds[value], 0.6) 
                setSoundMaxDistance(sounds[value], 45)

It won't play because you're only playing it if the sound doesn't exist.
