and repeated, if you want it to happen more than just once. Oh, and if you want the napalm burnin' to stop at some point, just put something like NOT(napalmStop) in the Condition line, and when you want the fire to stop, just add a simple: napalmStop=true into the equation :-D
(you might need to define napalmStop first though, so just put napalmStop=false somewhere and you should be fine)
Wolfrug out.
