Tuning children's journal to appear in inventory on age up

Hi, I'm trying to tune the children's journal item to appear in sims' inventory when they age up from toddler to child, the same way that homework books automatically appear in the inventory when they age up. This is my first time trying to tune/mod. I looked at "components of an EA object" and "How to Make a Basic Change to an Item's Tuning". 

Basically I took this section of the homework tuning and put it in the journal tuning:

<U n="_components">

<V n="affordance_tuning" t="enabled">

<U n="enabled">

<L n="affordance_map">

<U>

<T n="key">13855<!--Put_Item_In_My_Inventory--></T>

<U n="value">

<L n="tests">

<L>

<V t="sim_info">

<U n="sim_info">

<V n="ages" t="specified">

<L n="specified">

<E>CHILD</E>

</L>

</V>

</U>

</V>

</L>

</L>

</U>

</U>

</L>

</U>

</V>


I edited the tuning as shown in the basic change tutorial, then tried to test it in a new game and nothing changed - no journal in the kid's inventory when I aged them up with MCCC.

I also have no idea how to show you my work, so any assistance with that is also appreciated.
