my boxing timer

This has been my first attempt at programing a micrcontroller or programming from that matter.I box so i made a boxing timer which times either a 3min round or a 2min round with a 1min rest. Buzzer to end and start round and two leds green and red to indicate round or rest. I though id post the code as im sure u experience ppl could show me a far easier way of acheiveing the same result with less code.

There's a thousand different ways to do this. Whatever works for you...

Thanks for you rely skimask. You have saved me from a lot of "if endifs" on my next timer.

16f628a problem

My boxing timer has been working fine on a 16f84a. I have changed to a 16f628a and have had a headache ever since. Managed to sort most of the problems out. However both my green and red leds go on at the same time if my round switch is low. works fine when my round switch is high. so i cant switch between rounds. i have looked at the data manual and have found no reason for the porta bits to affect each other like this.
Does any one have any ideas????

ANSEL, CMCON, any of those applicable?

To try and fault find i have stuck leds on my outputs porta 0 1 2. And wrote a program to light them one at a time with a 1sec delay. Even this doesnt work. One of the leds doesnt light one stays on at half brightness and the other led does what it should. Can anyone see why this program isnt working.

Got a pullup on MCLR? (i know you've got mclr_off)
Try an external oscillator and switch your clock modes.
Turn off your watchdog timer.
Just ideas...

time display

Finally got my boxing timer completed. Now i want to have a seven segemt display counting down the round and rest time. I have seen the schematics for multiplexing the displays, so no problems there. But as a complete proggraming novice with only one little project under my belt i havent a clue how to code it. Could any of you experience people give me a few pointers. Would be greatly appreciated.
