[AccessD] Trimmean Function in Excel - How to in Access

Thank you Lambert and Jim.   I was trying to use aggregate functions similar 
to the following formula that I have used in the past in Excel:

=(SUM(A1:A5)-MIN(A1:A5)-MAX(A1:A5))/MAX(1,COUNT(A1:A5)-2)

and was having some trouble with getting the system to do what I need.

Thank you for your help.  Thought maybe there was a function that I didn't 
know about.
