Triggeraction Problems

[cbk1994]

I'm using a DB NPC, I need to trigger it from a class that the DB NPC is joined to.
The DB NPC's image is block.png

Here's the trigger (clientside)

PHP Code:

triggeraction( this.x +.5, this.y +.5, "BuyWep", [...] ); 


Here's the serverside onAction thing

PHP Code:

function onActionBuyWep( [...] )
{
  player.chat = "trigger2";
  [...]
} 


What am I doing wrong?
