   Try simply:

bioAnswers:HashMap( this["HEARING"] == "Y")

   Or

bioAnswers:HashMap( bioAnswers["HEARING"] == "Y")

    Also, I will not comment on the merits of using (or not) abstract datastructures as facts, as this was discussed in previous threads already... just in case you are unaware of such issues, I suggest you take a look at the archives.

It would help if you specify what the exact error message you are getting.

Have you imported the required classes?

I got a CompileException when run the following rule.
 
when
                bioAnswers:HashMap(bioAnswers.values["HEARING"] == "Y")
                reviewMsgs:LinkedList(size >= 0)
        then
                reviewMsgs.add("Hearing");
 
 
It will be very helpful is anyone of you rectify my mistake.
 
Thanks,
