function onactiondoublemouse problem

[callimuc]

hey guys im currently working on a script and i got a fail which i didnt know how to fix. this is pretty easy i guess but i dont have any idea how to fix

PHP Code:

function onactiondoublemouse () {
  say2 say "/buy hat1" for this hat;
} 


also tried this:

PHP Code:

function onCreated() {
  this.buycmd = "/buy hat1";
}
function onactiondoublemouse () {
  say2 say "this.buycmd" for this hat;
} 


i placed this in a npc which is playing a gani that only shows the hat (too lazy for icon). could that be the problem? because i also tried to put it into a noob npc which hat the same script (just other text):

PHP Code:

function onActionDoubleMouse() {
  say2 test;
}
