Could some one here tell me how to resolve the problem it says duplicate DecimalToString Dos that mean i cant use a macro twice in the same program if yes how to print more than one number Thanks in advance

;-----The macro to print a decimal---------;
DecimalToString macro numToBeprinted
     ; start of the macro
      push ax 
      push bx
      push cx     ;saving ax, bx, cx, dx to the stack
      push dx
          xor cx, cx  ; this basically do this: cx = 00000000
          mov ax,numToBeprinted  
          mov bx, 10d 
loop1: ; label we'll be using for a loop                      
          xor dx, dx 
          div bx     
           push dx   
           inc  cx    
           cmp ax, 0   
           jnz loop1 ; loop until ax = 0
           mov ah, 02 
loop2: ; another label which we'll use use to create another loop

Hey guys i geuss i discovered my mistake ..i will tell so that some one will benefit...Actually since i am using a macro which is different than procedure ,it is considered as an extension of the program so that is why i got "Duplication " To solve such problem just type local label1, many labels you want at the beginning of the macro .
