Problems with self-grabbing

[Dragon5]

I'm trying to figure out how to do the self-grab, but it keeps cancelling out. I can't seem to find the problem.
This is an attempt at the method brought up on YinYin's "Counter Skill" thread


Code for spawning the object and the action intended:

DC-Code: <frame> 124 defend pic: 56 state: 7 wait: 0 next: 999 dvx: 0 dvy: 0 dvz: 0 centerx: 37 centery: 79 hit_a: 0 hit_d: 0 hit_j: 0 hit_Fa: 235 hit_Fj: 247 hit_Uj: 275 wpoint: kind: 1 x: 46 y: 51 weaponact: 21 attacking: 0 cover: 0 dvx: 0 dvy: 0 dvz: 0 wpoint_end: bdy: kind: 0 x: 20 y: 19 w: 38 h: 60 bdy_end: opoint: kind: 1 x: 11 y: 4 action: 390 dvx: 0 dvy: 0 oid: 204 facing: 1 opoint_end: <frame_end>   <frame> 125 defend pic: 56 state: 7 wait: 2 next: 110 dvx: 0 dvy: 0 dvz: 0 centerx: 37 centery: 79 hit_a: 0 hit_d: 0 hit_j: 0 hit_Fa: 235 hit_Fj: 247 hit_Uj: 275 wpoint: kind: 1 x: 46 y: 51 weaponact: 21 attacking: 0 cover: 0 dvx: 0 dvy: 0 dvz: 0 wpoint_end: bdy: kind: 0 x: 20 y: 19 w: 38 h: 60 bdy_end: cpoint: kind: 2 x: 10 y: 79 fronthurtact: 299 backhurtact: -299 cpoint_end: <frame_end>

The object's code:
