As far as I know (still on HFM 4.X!), HFM doesn't have a predefined average function. You will need to define a new function in your rules as shown below. I got this from tech support a while back. The parameters are a little different to what you have in your example so you may have to tweak. Is the "3" in your example the period number?
Function Average(strPOV,strFreq)
     DIM nPERIOD
     DIM strCUM
     DIM i
     If strFreq="PERIODIC" Then
          If HS.PERIOD.ISFIRST=TRUE Then
               nPERIOD=1
          Else
               nPERIOD=2
          End If
     ElseIf strFreq="YTD" Then
          nPERIOD=HS.PERIOD.NUMBER()
     Else
          EXIT FUNCTION 'Nothing to do -
     End If
     For i = 0 To nPERIOD -1
          If i= 0 Then
               strCUM = strPOV &".W#PERIODIC"
          Else
               strCUM= strCUM &"+"& strPOV &".W#PERIODIC.P#CUR-"&i
          End If
     Next
     Average = "(("& strCUM &") / "& nPERIOD &")"
End Function
