Very Simple Backpack System

Well i was bored tonight so i decide to make a very easy hero backpack for the world edit users who want a backpack but dont have to spend lots of time makeing it work.

It is a very simple system and has some draw back but overall it gets the point across.
The draw backs that i see as most promenent are:
If u have a charged item and switch from your back pack to your regular inventory it will reset the charges.
The only way to put an item into your backpack is to drop the item on the ground then open your backpack and pick up the item.

but otherwise it seems to work fine
Please give me feedback as to how it works for you and if you find any other problems also tell me
Alright here it is:

This is really useful but it would be so much more useful with multiple pages. I tried to do this but mine ended up as a complicated mass of triggers, but it did work, however it would be no use to anyone who wants to make multiple pages because it is done in a very inefficient way.

sounds cool!

Yea i know its has its flaws but it is very simple and easy for someone who doesnt understand triggers very much and needs a backpack system im still trying to make it alittle more stable but keeping it simple.

Ok here is an updated one this works with as many players as you want. The first one if 2 players use backpack at same time it sometimes gets confused.
