I am having trouble working with this add routine

I am writing an add-on program for my assembly language class in Easy68k, but I have the same problem. Whenever I run the program, it allows me to enter up to 10 numbers (the allocated size of my array), and then displays a message saying that it is being calculated, but then I get an endless printout of y using umlauts. Any problems that you can see right away on the road with my program that would make it do this?

I was looking for syntax for routines because I am sure that this is what I am doing wrong, but I can not find anything.

ORG $2000
ARRAY   DS.W    10
ZDONE       DC.W    'Enter values. Zero when done.'
FULL        DC.W    'That is all the input allowed. Calculating sum now...'
OERROR      DC.W    'The values you entered caused an overflow condition.'
REPEAT      DC.W    'Do you want to repeat? [0=No, 1=Yes].'

START       ORG     $2800

MAIN    LEA         ZDONE,A1
        MOVE.B      #14,D0          ;
        TRAP        #15
        LEA         ARRAY,A0

        MOVE.B      #0,D3
INPUT   MOVE.B      #4,D0
        TRAP        #15
        MOVE.W      D1,(A0)+
        BEQ         SUB
        ADD.B       #1,D3
        CMPA        #$2012,A0
        BNE         INPUT
        LEA         FULL,A1
        MOVE.B      #14,D0           ; Outputs the FULL string
        TRAP        #15

SUB     SUB.W       A0,A0
        BSR         SUM              ; Begins to calculate sum

        CMP         #1,D0
        BNE         NoV
        LEA         OERROR,A1
        MOVE.B      #14,D0
        TRAP        #15
        BRA         AGAIN

        BEQ         START
        STOP        #$3800

        ORG         $3800        
SUM     LEA         ARRAY,A0

        BRA         RETURN
        CLR.B       D0
RETURN  RTS
