Problem with IR Pair circuit?

I went through Chapter 7 on navigating with IR headlights. The IR pairs worked after going through Activity #1. They didn't work after going through Activity #2. One IR pair worked and its LED was off until I place my hand in front of the IR pair. The other IR pair didn't work and its LED stayed on. I tried checking the circuits and the PBASIC code. Do I have defective parts?

·· Try jumping temporarily to page 238 and building just the circuits listed there and use the code on the following pages to test the IR system by itself.· Be sure to observe the polarity of the IR LEDs.

·· How about posting your code?· Attach it to the message.· Perhaps one of us with a BOE-Bot can try the code on our hardware and see what's up.· It might be something in the software too.
