On server event function not appearing

Hi all

I am trying to use a remote event by fireing it on a local script and detecting it on a server script but when I try to detect in on the server script I am not able to get to do the function OnServerEvent.
It wont appear in the little box.

Thank you

It could just be that the intellisense isn’t updating. Have you tried finishing then running your code despite the autocomplete not showing up?
