RCTIME does not appear to work for me

RCTIME does not appear to work for me. I have the "What's a microcontroller student guide" and have been having a great learning experience. I have hit nearly a dead end on Chapter 5, "Measuring Rotation". I successfully completed PolledRCTimer.bs2. It worked but using the ReadPotWithRcTime.bs2 does not - it just sits there, green light on. I tried looking for RCTIME in Help,copied the program and pasted it into mine, it does not work. This is the program:

' {$STAMP BS2}
' {$PBASIC 2.5}

result VAR Word

HIGH 7 ' charge the cap
PAUSE 1 ' for 1 ms
RCTIME 7, 1, result ' measure RC discharge time
DEBUG DEC ? result ' display result
END

That's it - does nothing - seems caught in a loop (activity LED stays on). I can use the same RC combo in my original, but not in this program with RCTIME.

Any comments. This is really bothering me. Direct cut and paste.

Thanks.

Figured it out. The raw program did not count nearly as fast as RCTIME. Using the RC values I had for the crude RC Time, I went over the WORD max value. decreasing the values fixed it.

Now i have another question.
