averageifs with 3 criteria

[Crowie_12]

Hi all,
I am having problems sorting out a formula that can include all of my criteria.
I need to find the average (column C- RR Interval) only if there is more then 2 values recorded in the past 7 days (Column B) for a participant (Column A- Name).
Example is below:

[TABLE="width: 357"]

What I have so far is AVERAGEIFS(C:C,B:B,"<="&B2,$B:$B,">"&$B2-7,$A:$A,$A2) .... but this averages all values even if there is 2 or less values between the two dates.

Any help would be appreciated.
