Define agent with parameter (%) and delay time in main is based of it. (Anylogic)

i'm still very new at Anylogic but really enjoying it so far.

I have a simple model which has a separate Agent called 'Passenger'. Inside the Passenger I have a parameters called 'WITH_CHILDREN' which it's default value is randomTrue(0.5).

In my main process, I would like the Passenger that results TRUE for 'WITH_CHILDREN' to take longer at a specific delay process.

I thought it would be something like (inside the on enter action of the delay):

if(passenger.WITH_CHILDREN == true){

    delayTime = triangular(1,5,15);
else{
    delayTime = triangular(0,1,1.5);
}

However there are many errors with this :( I would like to link it from the Agent as oppose to setting the percentage in the delay as I have future percentages parameters that will be used on other delays.... If that makes sense.

Any help will be appreciated, thanks! :D
