Need help on start /stop on single switch with pic micro controller

Hi
Any one plz help me on this code

5 led output (for delay status)

2 switch i/p

1 relay output

5 led status( 5min, 10min, 15 min 30 min, 60 min) delay

one switch for select delay and another switch for on/off (relay)

problem is on/off function not working properly ,some times working some times not
can anyone help me simplest way or bugs

Sam, just as a suggestion. First Edit this and put it in Code Tags; it's the Gear symbol next to the smilies in the tool bar. Second / comment out what all calls on all lines as to what your expecting them to do

It may be easier to get the right help. I'm not qualified; good luck.
