How am I supposed to make these parameters work even though they're in separate scripts?

I'm using parameters with a remote event so that it can transfer info from client to server, but for some reason, I still get a red line in the script (marked with a note.)

Local Script Line

PunchHit:FireServer(hit.Parent)

Server Script Line

local function PunchHit(player,hit.Parent) -- the ".Parent" line here gets a red line
end

PunchHit.OnServerEvent:Connect(PunchHit)

How can I fix this and make it work from separate scripts?

local function PunchHit(player,v) print(v)
end

PunchHit.OnServerEvent:Connect(PunchHit)
