Any idea why this RemoteEvent and FireServer isn't working?

I'm trying to call a remoteEvent on the server called FillBackpack, but when I do I get the error:

"FireSever is not a valid member of RemoteEvent"

I tried looking at the wiki and other answers but to no avail obviously.

This is what I have currently:

LocalScript

workspace.Scripts.ServerDataExchange.FillBackpack.FireSever:connect()

I also tried this in LocalScript:

workspace.Scripts.ServerDataExchange.FillBackpack:FireServer()

ServerScript

script.FillBackpack.OnServerEvent:connect(function(player)

end)

Thanks for reading :)
