To anyone who can help,
I have a Excel file that I need to extract out the Min value and the
Max Value out of a specific column looking only at every ninth record
starting with row one (a1). It will look like this:

a1) 90
a2) 1
a3) 2
a4) 3
a5) 4
a6) 5
a7) 6
a8) 7
a9) 8
a10) 100
a11) 1
a12) 2
a13) 3
a14) 4
a15) 5
a16) 6
a17) 7
a18) 8
a19) 110

I only want to key on the "90","100,"110" and find the min value out
of these which is "90". Hope this makes sense. Can anyone tell me who
to use the "Min" command to do this keying on every ninth record only
in column "A"? Then I need to do the same principle but instead of min
I need "Max" which would be "110". Thank You in Advance.
