Script compilation errors and a question : V

First, the error(s)!
For some reason the compiler doesn't appear to like assigning the contents of a property to a variable...

Here be the code:

Here be the errors:

So, thoughts? I've tried doing the assignment on a separate line as well with the same error.

Second, question!
Is it possible to modify the state of a script running on an actor, the one above as a matter of fact, from another script e.g. Player.scriptname.GotoState("foo")? Or would I be forced to "poll" for the changes I need to look for through use of the RegisterForUpdate() functionality? I'd really prefer not to use the second route if at all possible.

I wish there was a Spell version of OnObjectEquipped/OnObjectUnequipped.
