Solved Adding items to minecart chest

[Aberforth]

Hello,

By right clicking an armor stand the player can open a GUI:

on right click on entity:
    if name of clicked entity is "container":
        if {container_open::%event-entity%} is 0:
            send action bar "&7Opened container" to player
            open chest with 6 rows named "&fContainer" to player

I would want the player to be able to add items to the GUI. I know I could do it if it was a chest:

on right click on chest:
    if player's tool is torch:
        add 1 torch to event-block's inventory

But what should I do to achieve the same effect with a GUI like above instead of an actual chest?

Maybe this:

set {Tool} to player's tool
{Tool} is not air
#stuff

Maybe this:

set {Tool} to player's tool
{Tool} is not air
#stuff

Sorry, I don't get it, can you explain further? What am I supposed to put in #stuff ?
[doublepost=1594717204,1594655707][/doublepost]I decided to change the idea a little bit, instead of using an armor stand I'm gonna use a minecart chest. It has an inventory so I thought it'd be easier.

on right click on minecart:
    add 1 stick to the inventory of the clicked entity

For some reason, this doesn't put items in the chest. Any ideas?

Okay I tried this:

on right click on minecart:
    set {_e} to event-entity
    add 1 stick to {_e}'s inventory

And it works so I believe I'll be fine from here. The problem is solved.
