Not sure why this isn't working!

Avg_Minutes_Diff keeps appearing blank, along with hpp.macaddress
Give this a try

If it doesn't work, can you confirm if your subsearch returns results on it's own (run it separately)?
Just out of interested, have you tried putting the hpp.macaddress=00-16-E4-12-9B-4B
as hpp.macaddress="00-16-E4-12-9B-4B"
(e.g. with quotes)
