Event not greenlit help

I have a client even Im trying to call via the server, but I get this in the console:

A client tried to send an event of type updateSiren, but it was not greenlit for client invocation.

RegisterNetEvent(‘updateSiren’)
AddEventHandler(‘updateSirenTone’, function(PID, tone)

end)

.-. calling a client even as a server event

Your event names are different.

updateSiren and updateSirenTone
