AI Paths and routes

Hey,

I am coding my AI man to walk a path, which is in a simgroup called patrol, which in that has 3 routes (route1,2 and 3).

I'm having trouble getting the ai to switch to a new path when he has finished his circuit. Here is the ai code I have so far:

function spawnPatrolonPath(%patrol){
%ai = new AIPlayer(){
dataBlock = AIBasicDB;
arcOfSight=60;
sightRange=50;
approachRange=10;
state = "PATROL";
aiPlayer = true;
patrol = %patrol;
currentNode = 0;
currentPath = 1;
};
MissionCleanup.add(%ai);
// Assign my routes to variables I can use
%node = %patrol.getObject(%ai.currentNode);
%ai.setTransform(%node.getTransform());
// So my AI doesnt run, but does a steady patrol
%ai.setMoveSpeed(0.5);
%ai.moveToNextNode(%aiPlayer);
}

function AIPlayer::moveToNextNode(%aiPlayer){
if (%aiPlayer.CurrentNode < %aiPlayer.patrol.getCount() -1){
%aiPlayer.CurrentNode++;
}
else{
%aiPlayer.CurrentNode = 0;
}
%aiPlayer.moveToNode(%aiPlayer.CurrentNode);
}

function AIPlayer::moveToNode(%aiPlayer,%nodeIndex){
// Obtain a reference to the node
%node = %aiPlayer.patrol.getObject(%nodeIndex);
// Move to node and slow down as node is reached
%aiPlayer.setMoveDestination(%node.getTransform(),true);
}


function AIBasicDB::onReachDestination(%this,%aiPlayer){
// Added to determine if the NPC had completed a full circuit
if (%aiPlayer.currentNode == 0){
%this.onEndOfPath(%aiPlayer,%aiPlayer.patrol);
}
else {
// Move to the next node on the path
%aiPlayer.moveToNextNode();
}
}

function AIBasicDB::onEndOfPath(%this,%aiPlayer,%patrol){
echo("***PATH END***");
%aiPlayer.currentPath++;
}

function AIBasicDB::Think(%this,%aiPlayer){
%aiPlayer.setAimObject(LocalClientConnection.getControlObject());
%aiPlayer.getDataBlock().schedule(1000,"Think",%aiPlayer);
}
