Book system Options

[atlus]

Okay now that I have a new computer I am ready to start a project again. Problem is I want to make a book system like so:
Move Event...: Hero ,FaceRigh
Fork optn:Book of Knights Item Got
Memorize BGM
Play BGM: Tavern
Messg: You read an interesting book about the knights of
old.........
Play SE: increase
Variable Ch:xxxDefense up Set,Samson Defense
Variable Ch:xxxDefense up +10
Messg:Your defense increased

Else Case

End Case
Play Memorized BGM

So I made an event somewhere else in the room that will give me the book,sat on the couch the message came up so so far so good but then after that I checked my defense and no change in it. So can someone check and see what is wrong. I am sure it is in the varible change part but I dont know what I did wrong. Also I am planning on expanding on this too like say fpr example when You read this book not only will it increase defense but also courage and depending on your courage certain jobs and extra events will become available. Kinda like persona 4 golden.
