Help with ACS Scripting

[TheSuperPlayer]

Please I need help with this... I'm doing a project for a mod where I am setting a to activate a reload sequence for a shotgun (a SPAS-12) in wich i have serious problems to load acs scripts (I know that this command exists in (g)zdoom but doesn't exist in skulltag/zandronum). I created the lump loadacs and i made the compiled acs between the markers A_START and A_END but the game still not load the scripts. I've tried everything and I was out of ideas... Please check the wad and tell me what am I doing wrong

You need to create a new DECORATE for the shotgun.

The rest will be explained, since i'm not good with DECORATE.
