  If you look at the TwineScript operators section of the Harlowe documentation you will see that if you add two arrays together using the plus character the resulting array will contain the items of both arrays the other arrays. The following example uses that information to add an item to a $inventory array.

  Start with an empty array
  (set: $inventory to (array:))
  
  Adding a "Sword" to the inventory:
  (set: $inventory to it + (array: "Sword"))
  You have: $inventory
  
  Adding a "Shield" to the inventory:
  (set: $inventory to it + (array: "Shield"))
  You have: $inventory
  
  Remove the Sword from the inventory:
  (set: $inventory to it - (array: "Sword"))
  You have: $inventory

  Alright, I think I understand that much, thanks!
  
  But then, how do I get these changes to reflect properly in the sidebar? It's now showing like so:
  

  [Youre carrying:0]
  

  
  It says this even though I have the if-statement that should tell you that you aren't carrying anything.
  
  And lastly, how do I keep the story contained to the right? The text moves under the sidebar once past it.

  If you're using greyelf's code, did you change the sidebar code to $inventory rather than $inv

  (if: $inventory's length is 0)[<b>You aren't carrying anything!</b>]
  (else:)[You're carrying:$inventory]
  

  
  The fact that it's printing 0 suggests the variable hasn't been initialised.
