Go4Expert - help my error

hi guys, im having problem in making my fibonacci sequence, so far i've had the code to do everything i wanted except when i try to add eax with ebx, 00000008 + 00000005 it resulted 0000000D instead of 00000013. i wonder what did i do wrong. this is my first time taking the course. here's the code

Code:



INCLUDE C:/Irvine/Irvine32.inc



.data

counter DWORD 12

int1 DWORD 0d

int2 DWORD 1d

nextNum DWORD ?





.code

main PROC

        

        mov                eax,int1                ;

        call        DumpRegs                ; showing F0 

        mov                eax,int2                ;

        call        DumpRegs                ; showing F1

        mov         ecx,11                ; setting the amount of loop



        

L1:

        mov eax,int1                ; eax = 0

        mov ebx,int2                ; ebx = 1

        add        eax,ebx                        ; eax = 1 + 0 

        mov nextNum,eax         ; nextNum = eax = 1

        mov int1,ebx                ; eax = 1

        mov int2,eax                 ; ebx = 1

        call DumpRegs                ; show the registers

        

        loop L1



                        

        exit

main ENDP



END main

thanks
