Easy Question but I feel stupid.

Because you are disregarding a value you need to include -1 to the count bit otherwise you divide by 7 instead of 6.
Also wrap each bit of the divisino formula in their own set of brackets to ensure these bits are calulated first then the divde bit is done last.

=(sum(range)-min(range))/(count(range)-1)

Like this...

Data Range

	A	B	C
1	100	-----	94.16667
2	95
3	85
4	100
5	95
6	90
7	85

This formula entered in C1:

=(SUM(A1:A7)-MIN(A1:A7))/(COUNT(A1:A7)-1)

The placement of the ( ) dictate which calculations have precedence.

Maybe something complicated. Please look to attached file. And you know if you want to discard two smallest numbers its easier by this function.

edit: Sorry my bad stupid solution, excel in your example discard 2 smallest numbers.
