Script with delay and interrupt it. How?

[legolas2069]

Hi! I'm triying to do the next:

Variables: Trigger, group address B, group address C.

I have a trigger, when this trigger switchs ON, B must switch ON inmediatly and C must switch ON with a delay of 3 minutes. Also, when the trigger switchs to OFF, C must switch OFF inmediatly and B must switch OFF with a delay of 10 minutes.I don't know how to do when I change the trigger value under the 3 or 10 minutes delay time.

Any way I can achieve this?

Thanks in advance.
