    Hi, Nichole.

    Sorry... I must have left out the label when I typed up that
    code.  The "CLEANUP" label should appear just before the "MOVF
    PULSE1S,W" line (right after the two line of comments).

    How long does it take for the capacitor to discharge in your
    circuit?  At 4 MHz, the value in PULSE1S will be equal to 1 count
    per 6 microseconds... So if the cap takes longer than 1.5
    milliseconds to discharge, that PULSE1S value will be 250.
