So I am getting an error...

12:37:34.800 - Argument 2 missing or nil 12:37:34.806 - Script 'Players.Player1.PlayerGui.ScreenGui.frameInventory.LocalScr', Line 1 12:37:34.811 - Stack End

This is the script:

local Inventory = game.Workspace.functionLoad:InvokeServer()

I am trying to receive a table, but why does it ask for an argument?
