Manage items of chest

[SantiagoCervera]

I give up! I don't know how to manage items from a chest:

I want to remove a certain amount of items from one chest and add another items to another chest.

{factories::%loop-index%::input} => This is a chest block
{factories::%loop-index%::input::item} => This is an item

#Add 10 of item to chest
 add 10 of {factories::%loop-index%::input::item} to {factories::%loop-index%::input}

#Remove 10 of item from chest
remove 10 of {factories::%loop-index%::input::item} from {factories::%loop-index%::input}

What I tried:
-Replace variables with constants and still not work.

Whats happens?
- No compilation errors or warnings.
- Line execute because i have a debug line after line 3 and yes is inside the condition.

If i missing something tell me please i gona crazy right now jaja
