Go4Expert - problem with numbers

i am making a clock that is operated by a 80x86 MP, it has a setting function which i wrote twice, but i dont think any of them work.
here they are:
1.

Code:

SET:                        ;START OF SET

MOV AH,00H

INT 16H

CMP AL,6   

JAE SET

MOV BL,AL

MOV AH,0H

INT 16H

MOV CL,4

SHL BL,CL

ADD BL,AL



MOV DX,37AH

MOV AL,00H

OUT DX,AL

MOV AL,BL

Code:

SET: ;START OF SET

MOV AH,00H

INT 16H

CMP AL,'6' ;6 WITH QUOTES OR WITHOUT? - CHECK IF THE NUMBER IS GREATER THAN OR EQUAL 6

JAE SET







SHL Ax, 1                                  ;Multiply AL by two                   -alot faster than mul

MOV bx, Ax                                                       ; Save 2*AL for later

shl Ax, 1                                                             ;Multiply AL by four

shl Ax, 1                                                           ;Multiply AL by eight

add Ax, Bx                                                    ;Add in 2*AL to get 10*AL





MOV BL,AL



MOV AH,00H

INT 16H

ADD BL,AL
