Default Average,Countif

OK. Column B is set up like this:
ALB
1st
2nd
3rd
4th
AP
1st
2nd
3rd
4th
ASD
1st
2nd
3rd
4th
Each identifier has 4 subsequent sub-catagories, labled 1st, 2nd, 3rd, 4th.
What I need to accomplish is first calculating an average of all the
identifiers (ALB+AP+ASD/3) not counting any 0 or empty cells. Then repeat for
the 1st's, 2nd's and so on. Since all of the sub-catagories are the same the
only way to identify is by the idendtifier thus the Mod(row()). I'm not stuck
on doing it this way, open to suggestiongs.

Thanks,

MT.

If you were to give us a more detailed explanation of what cells you want to
average it would help.

Using your original formula you want to average rows 3, 10, 17, 24, 31 etc.

Now you want to copy the formula down. What rows do you want averaged for
this? And how many rows down will the formula be copied to? Is there any
unique identifier to what rows need averaged? Maybe something like a date.
I'm guessing that since you're working in increments of 7 this is for
weekdays or weekly data? So, you want the average of all Mondays? If there
were an identifier like this it would be much easier than calculating
offsets using MOD(ROW()).

It figures that the last row I need would be the problem. When I tried
your
suggestion it gives me a circular reference. I think this is because of
this
=IF(C11,INT(C1/100)*60+MOD(C1,100),"") which is in cell S1. It changes
the
time from say 111.00 to 71 seconds. So if there were a way to incorporate
{=AVERAGE(IF((MOD(ROW(CLM10000!$C$3:$C$640),7)=3)* (CLM10000!$C$3:$C$640<""),CLM10000!$C$3:$C$640))}
with ,=IF(C11,INT(C1/100)*60+MOD(C1,100),"") it might help.

Is that possible?

Well, you can't get to 7 with that formula. The MOD function is used to
count the rows in increments of 7. Everytime the 7th row is reached the
mod
restarts at 0 and starts to count "up" again. Like this:

3,4,5,6,0,1,2,3,4,5,6,0,1,2,3,4,5,6,0

If you want the same pattern, every 7th row, *starting* from the 3rd row
and
then incrementing as you drag down, maybe this:

=AVERAGE(IF((MOD(ROW(CLM10000!C3:C$646),7)=3)*(C3: C$646<""),C3:C$646))

Thats exactly where I'm at. I need to be able to get to 7.

How far down do you want to copy it?

You can have the MOD comparison increment from 3 to 4 then 5, 6. When
it
increments to 7 or greater you'll get errors.

{=AVERAGE(IF((MOD(ROW(CLM10000!C3:C646),7)=3)*(C3: C646<""),C3:C646))}

I have this entered in cell Adjust PtsC1. As I understand it it
gives
the
average of a column using the data in every 7th row, starting with
the
3rd
row. It seems to work well, but my problem is when I try to drag it
down
(even with Ctrl+Drag).

I've changed the formula
{=AVERAGE(IF((MOD(ROW(CLM10000!C3:C646),7)=4)*(C3: C646<""),C3:C646))},
so
it
should use every 7th row starting with the 4th row. Is there a trick
to
copying, pasting or moving Array formulas?

Any help? Thanks!
