triggering beetween wnpcs

[Chompy]

Well, I've been experimenting, but I can't get something like this to work..

// -Master

PHP Code:

//#CLIENTSIDE
function onCreated()
{
  this.wnpc = "Chompy/Test";
  triggerserver( "gui", this.wnpc, "actiontest", "foo");
} 


// Chompy/Test

PHP Code:

function onActionServerside()
{
  if ( params[ 0] == "actiontest")
    echo( params[ 1]);
} 


This isn't working for me, anyone have any ideas?
I dunno if I am doing anything wrong..
(Doesn't output the echo in rc chat)
