Can someone view this VERY EASY palette blocks / code ?

Thats the only error and I have exactly the same code as  ETHproductions screenshot.

Yes. But I would like to see it from yours to check (just in case). And what you gave me definitely wasn't the whole error.

It sounds like your problem comes from setting the Actor attribute to the very same Actor attribute. In the Created event, you must press 'Choose Actor...' and pick the actor that you want to check the alive-ness of.
