Attempt to index local 'sender' ( a nil value ) for shop script

[lua]
function GiveaDeagle(sender, command, arguments)

if sender:Money_Get() >= 400 then

	sender:Give("weapon_interloper_deagle")
	
	sender:Money_Take( 400 )
	
	return true
	
else

	return false
end

end

concommand.Add(“GiveMeAGun” , GiveaDeagle() )[/lua]

At line 40, it’s giving me this error "attempt to index local 'sender ’ ( a nil value) ". I’m trying to let players buy weapons and then have their money taken away but after 2 hours of just messing code around, i’m stuck on this. My brain is fried at the moment, can anyone please help me solve this?

Remove the “()” from “GiveaDeagle” in the concommand.Add.

Many thanks. I also need to have the trader tell the player doesn’t have enough money if the player tries to purchase something that’s too expensive. How would I modify this code to trigger the chat.AddText function? Here is what I have at the moment.

[lua]

PistolButton.DoClick = 
function() 
	
	if RunConsoleCommand("GiveMeAGun") == false then

	chat.AddText(Color(255,255,128), "Merchant: ",Color(255,255,255), "Guns don't grow on trees, sweety. You'll need more money for that one." )
	end
end

[/lua]

You’d have to do something along the lines of [lua]function()
If (LocalPlayer():Money_Get() < <Money Here>) then
–Chat.AddText Shit
end
end[/lua]
