AOZ Studio V1 (TBD bugs clean/-> V2)

Here's the code.
This will compile and run as it is, but causes a runtime error. If you omit the line that starts "Right$", no error.

Screen Open 1,400,300,32,Lowres
Print "Hello World"

Dim SC(6)

Procedure SCOREUPDATE
   Shared EXTRAMAN,SCORE,SC(),LIFE
   If SCORE/30000>EXTRAMAN
      LIFE=LIFE+1     
      EXTRAMAN=SCORE/30000
//      LIFEDISP
   End If 
   If SCORE>1000000 Then SCORE=SCORE-1000000
   Autoback 1
   SCORE2$="0000000"
   SCORE1$=Str$(SCORE)
   SCLEN=Len(SCORE1$)-1
   SCORE1$=Right$(SCORE1$,SCLEN)
   Right$(SCORE2$,SCLEN)=SCORE1$
   For N=1 To 6
      If SC(N)<>Asc(Mid$(SCORE2$,N+1,1))-48
         SC(N)=Asc(Mid$(SCORE2$,N+1,1))-48
         Paste Icon 32,160+16*(N-1),SC(N)+31

   Next N

End Proc

Here's the extract for application.jsvar self=this;

this.reset=function()
{
    self.vars=
    {
        SCORE2$:"",
        SCORE1$:"",
        SCLEN:0,
        N:0,
        :""          <<<----- This shouldn't be here.
    };
