LCD display not working properly

[dilpkan]

I am trying to write a simple code to enable password entry. I am using 16F877a and two line LCD module for display. I have written following code which gets compiled successfully however when I key in four digits they are not displayed on the LCD module.

OPTION_REG.7 = 0 ' PORTB Pullups.
TrisA = 0 ' PORTA, all outputs
PortA = 16 ' Turn off Buzer
TrisB = %11110000 ' PORTB.0-3 outputs, 4-7 inputs
PortB = 0
Define LCD_DREG PORTC
Define LCD_DBIT 0
Define LCD_RSREG PORTC
Define LCD_RSBIT 4
Define LCD_EREG PORTC
Define LCD_EBIT 5

LD1 var PortA.2
RL1 var PortA.3
BUZ var portA.4
cnt var byte
cnt2 var word

key var byte
col var byte
row var byte
keycnt var byte
pwOK var bit

keybuf var byte[15]
pwbuf var byte[4]
Pause 100 ' Wait for LCD to start

Lcdout $fe, 1, " HELLO " ' Display sign on message
Lcdout $fe, 1, " WORLD " ' Display sign on message

Pause 500 ' Wait for LCD to start

Lcdout $fe, 1, "Enter pasaward " ' Display sign on message

loop: Gosub Chk_KEYPAD: ' Get a key from the keypad
Lcdout $fe, $c0+1,1,$0f, #key ' Display ASCII key number
Gosub Chk_KEYPAD: ' Get a key from the keypad
Lcdout $fe, $c0+2,1,$0f, #key ' Display ASCII key number
Gosub Chk_KEYPAD: ' Get a key from the keypad
Lcdout $fe, $c0+3,1,$0f, #key ' Display ASCII key number
Gosub Chk_KEYPAD: ' Get a key from the keypad
Lcdout $fe, $c0+4,1,$0f, #key ' Display ASCII key number

Goto loop ' Do it forever
