PAA Parsing Working?

Can't seem to get PAA parsing in Google parser to work.

For result format I have:
$paa.format('$link,$anchor,$media,$question\n')

Also tried:
[% FOREACH paa -%]$link,$anchor,$media,$question\n[% END %]

In parser tester I confirmed query does have PAA in SERPs.

 

Thanks! I wasn't specifying the number of PAA to parse. Didn't realize the default was 0.
