my project Capacitive Sensing LED dimmer 12F1822 via PWM

rather than confuse hecklers fine and working project why not start a new thread that reflects your project and hardware more closely
say "using multi cap-sense inputs on a pic16f722a" .

there are many issues with your code starting from the tmr0 setup (prescaler ?) to a 100mS delay in the isr that will interfere with key scanning to such an extent to make success unlikely.

Okay. But if the timer0 source works for Heckler, why won't it work in mine? Everything seems to be working okay, except that I want it to be a single-shot occurrence on the 1/0 button, rather than a continuous loop, as it is for the up/down buttons. I thought the 100mS pause was the period that the count from timer 1 is occurring? Thanks. The reason I posted on Hecklers was because I was hoping to get some input from him.

Hello,
Another one...in your example (PIC12F1822) with the LATA and LATA.0 references, is there a way that I can implement the same function, still using the PIC16F722A device, uisng the B port instead?

ccp1con=12|((PW&3)<<4)

1. it keeps only the first two bits (Bit 0 and Bit 1) of the PW. Rest bits are set to 0
2. shifts left by 4 positions
3. Makes a Bitwise OR with the number 12 (binary 00001100) so to keep te bits 2 and 3 if they are set)
4. Places the result in ccp1con
