What does this error mean?

When I played my simulation, I got this error. What does it mean?

time: 85.459547 exception: FlexScript exception: Property "rank" accessed on invalid node. at MODEL:/BasicTE1>variables/messagetrigger

It means that in a line of code in the On Message trigger of Basic TE1 you are using the rank property on a node that doesn't exist. You've probably made a bad assumption in your code and you just hit a case where the object you expect to be able to reference is not there or is in a different place, etc.

I can't really give you anymore details unless you post a model.

I was searching to play "animation" when it was called "animation1"
