Toying with a new mod and trying to remember all the quirks of the CS. I've written this:

ScriptName 00ScareUndeadScrBegin ScriptEffectStart    If ( Player.GetAV Fatigue > 100 )             00GhostCasterRef.MoveTo Player 10 10 10             00GhostCasterRef.Cast 00ScareUndead Player    Else        Message "I lack the fatigue to use this power."        PlaySound MagicFailureSoundAlteration        Dispel 00ScareUndead    EndifEnd

It won't compile. I'm getting "Script command "00GhostCasterRef.MoveTo" not found." WTF?

Try changing your ref names from "00..." to "aa...", anything non-numeric.

Very simple fix - don't use numbers for your references.

00GhostCasterRef is bad.

use AAGhostCasterRef instead if you want it at the top of the list.
