Minimum count greater than zero

[alnav89]

I have a column of grades, I want to get the minimum grade that is greater than zero (in other words I do not want it to count zero as a minimum grade)... is there a formula that I can use? thanx in advance

If column A, A1 thru A7 has grades, then:

=SUMIF(A1:A7,">"&0)/COUNTIF(A1:A7,">"&0)
