What is not correct in this shit? :D

[Ronis]

Hello, i have a question, what's is not correct in this?

So basicly, on the old script was only one sound, now it's 4.

Something is not correct in server side because, when i put old script with only one sound, it's works, but this not.

Line 4, client side:

elseif exports.global:hasItem(source, 85) then -- sirens 

There can't be 'elseif' without an 'if' first.
