Can't find Lifespan
 

...Maya help says it's on the attributes editor in the "Lifespan Attributes" section. What lifespan section? Selected my container; It's not under fluidShape, fluid, time, or emitter. Neither can I add the attribute, the list has no "lifespan" or "particleLifespan".
..Render Attributes-> add dynamic attributes... don't see that either. Only Render Stats, but thats not it. ugh, am I missing something.

Is there another way to kill particles in a 3d container?
