Thanks for your comments

I changed the dbit to 4 , but nothing come out of the LCD , but LED is blinking
This is my first time working with 18F2550, is there any other mistake I made?

Code:
ASM
        __CONFIG    _CONFIG1L, _PLLDIV_10_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L
        __CONFIG    _CONFIG1H, _FOSC_HS_1H
        __CONFIG    _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L & _VREGEN_OFF_2L
        __CONFIG    _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H
        __CONFIG    _CONFIG3H, _PBADEN_OFF_3H & _MCLRE_ON_3H  & _CCP2MX_ON_3H
        __CONFIG    _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L  & _DEBUG_OFF_4L
        
ENDASM
