Supressing NOTICE output - mIRC Discussion Forums

I'm trying to suppress the regular output of a NOTICE with a remote script with a /halt command in it.
The remote script is being executed as expected, but the regular text still shows up.
Anybody know why and how I can prevent it?

Code:

ON *:NOTICE:Text to look for:?: {
  halt
}

try

Code:

on ^*:NOTICE:&lt;matchtext&gt;:?:{ 
  haltdef
  ;[color:green]any other code here... [/color]  
}

try with ^

ON ^*:NOTICE:Text to look for:?: { halt}
