Problems with SugarCube Inventory

I am currently using Twine 2.0.11 on browser and SugarCube 1.0.34 and I'm trying to implement this inventory system into my story: https://twinery.org/wiki/twine2:add_an_inventory_system

However when I go to pick up an item it does not show up in the Inventory menu I have made with a StoryMenu passage.

Any Help?

Will I have to move to a desktop version of the Twine program to use an updated version of SugarCube for this to work?
