Battle command pointers and general question

Okay, after a night of intoxicated button mashing and a days worth of cussing, I've somehow accomplished most of what was in that first paragraph... except turning Row into Item.

I've retargeted ever instance of Row I can find in C1 and C2, mutilated the Row cluster of code to make it go to the same block Item goes to and....

I get the throwing hands in the air, open text box where it should say what I just used and nothing else. Where the heck is the part that tells "Item" to open the menu and let you pick an item to use? I could really use some direction on this one, from what I understand it should have been in C2...
