This is the same exact code as on the LSL-Wiki, it has been converted to OSSL, therefore you will need to be the land owner and ossl (osnpcsay, osisnpc) functions must be enabled. The NPC will respond twice if your activeNPC ..extension script has "osnpcsay" commands in there which it is responding to, those SHOULD be disabled if you want racter to handle that. Example, Active NPC will respond to 'help' and so will racter so you will need to change that line in your ..extension script so it is not triggered. You can also disable any other osnpcsay commands in there as needed.
