I apologize in advance if I'm being an idiot, but would someone please put me out of my misery and tell me how to watch a variable while debugging in MPLAB?
All I'm trying to do is watch the value of an integer variable which should be changing as I change the voltage applied to a pin. I've copied part of the code in below incase it's relavent to my question (I want to know the value of "result"):

Code:

	while(1)
	{	
	
		OpenADC(ADC_FOSC_32 &
					ADC_RIGHT_JUST &
					ADC_12_TAD,
					ADC_CH0 &  
					ADC_INT_OFF &
                    ADC_REF_VDD_VSS, ADC_1ANA);
		ConvertADC();         // Start conversion
  		while( BusyADC() );   // Wait for completion
		result = ReadADC();   // Read result
  		CloseADC();           // Disable A/D converter
		
		
		
		if(result>50)
		{
			LEDPin = 1;
		}
		else
		{
			LEDPin = 0;
		}
	}

I am using a PIC18F2550 with a PICKit2, the MPLAB IDE and MPLAB C18 Lite compiler.
