Disc brake anti-rattle clips.

For some time I have had a problem with my front brakes clunking when I use them. About a month ago I found that I didn't have any anti-rattle clips installed. I bought a set from Rockauto which came in a set of four so I assumed that I needed all four of them... one on each end of the inner brake pad.
It made a tremendous difference. The brakes felt better than they have since the truck was new and the clunking noise was gone. It took about two days and the brakes began clunking again. I finally crawled under it yesterday to see what is up and lo and behold three of the clips are gone.
This time I went to AutoZone and bought a set of clips that came with new caliper guide pins. It came with four pins and two clips. Is there supposed to be one or two clips on each inner pad? If there is only supposed to be one clip does it go at the top or bottom? (Or does it matter?) How can I prevent them from disappearing again? I am certain that I had them installed correctly.

From what I can remember I believe there should be one on the bottom. They are tricky little bastards, make sure they are on right or they wont stay.

There should be 1 clip on the bottom of each inner pad.

Another brake question for you guys:

My ABS light has been on for years. While searching for the anti-rattle clip information I learned that you can get a code for faulty ABS. So I grounded the connector and got 12 blinks including the long one. According to Chilton's that is "fluid level switch grounded during a RABS stop."
Anyone know what this means and how to fix it?
