game:GetService("BackPack")
The above is just something I thought of maybe working. I am trying to make my own custom backpack, or inv for items that are in backpack to be stored there. I have removed ROBLOX's custom backpack, and made it so that when you click, or pres no 1, 2 etc it takes you to the slot. I just need to figure out how to make it check the players backpack. Something that just gets the stuf in a players backpack.

I am currently using a localscript
what is the cutsom GUI element? I have made my own backpack gui, and all that, but it only holds 5 slots
NinjoOnline, where it says to create a custom GUI element, I think you need to write where the tools go in the GUI.
