Tried to use a NULL entity! Error

I tried this code and it gives me a error.

ERROR > [line 31] Tried to use a NULL entity!

CODE>

[26] function updateClient(ply)
[27]    net.Start("StartingVars")
[28]          net.WriteInt(GMoney, 8)
[29]         net.WriteInt(GLevel, 8)
[30]          net.WriteInt(GEXP, 8)
[31]     net.Send(ply)

Where are you running updateClient? You need to give it a player

[GoldenLeopard]

in server

util.AddNetworkString("StartingVars")

GMoney = 50
GLevel = 1
GEXP = 0

GMoney1 = 50
GLevel1 = 1
GEXP1 = 0

function updateClient(ply)
	net.Start("StartingVars")
		net.WriteInt(GMoney, 8)
		net.WriteInt(GLevel, 8)
		net.WriteInt(GEXP, 8)
	net.Send(ply)
end


net.Receive("StartingVars",function(len, ply)
	GMoney1 = net.ReadInt(8)
	GLevel1 = net.ReadInt(8)
	GEXP1 = net.ReadInt(8)

	updateClient()
end)

and in CLIENT

function updateServer()
	net.Start("example")
		net.WriteInt(GMoney, 8)
		net.WriteInt(GLevel, 8)
		net.WriteInt(GEXP, 8)
	net.SendToServer()
end

net.Receive("example" , function(len)
	GMoney1 = net.ReadInt(8)
	GLevel1 = net.ReadInt(8)
	GEXP1 = net.ReadInt(8)

	updateServer()
end)

You need to pass ply as an argument, Go look at the code that you saw again and read through it.

You didn't ever give updateClient a player. Just do

updateClient( ply )

In the server file

Use code tags, either

[noparse]

or

[lua]

Back onto the topic, you have to call `updateClient` with a player argument. I can't really tell what you're going for though, considering your net message names don't match, and if they did it'd just create an inf loop.
