DarkRP Money Printers - Derma Panel Help

[vontiagaming]

Hey, does anybody know how i would make it so when i press USE on a printer it opens a Derma Panel?
I tried this.

function ENT:Use( ply )
	if self:GetMoney() > 0 then 
		ply:addMoney( self:GetMoney() )
		
		DarkRP.notify( ply, 0, 5, "You picked up " .. self:GetMoney() .. "!")
		
		self:SetMoney( 0 )
		
		local Frame = vgui.Create( "DFrame" )
    Frame:SetPos( 5, 5 ) 
    Frame:SetSize( 300, 150 ) 
    Frame:SetTitle( "Name window" ) 
    Frame:SetVisible( true ) 
    Frame:SetDraggable( false ) 
    Frame:ShowCloseButton( true ) 
    Frame:MakePopup() 
end

Thanks!

Here's an example: [url]https://dl.dropboxusercontent.com/u/26074909/tutoring/_zipped_code/acecool_npc_jointeam_example.rar[/url]

ENT:Use is server-side so you'll need to network a flag / message to the client, open it that way and if you want to click something that triggers something on the server, you'll need to network that data to the server.

Never trust client input either, don't trust the client to tell the server how much money they picked up...
