Syntax question: using worksheet functions on a subset of a 3-D ar

I have a 3D array that is (1 to 2, 1 to 24, 1 to 12)
first parameter is raw number vs. %
second parameter is hour of the day
third parameter is 5-min increment (within each hour)

I'm taking LAN reports and scraping them to do some bandwidth analysis (I
don't have control over the source data). I've got the data populated into my
array, representing one data point every 5 minutes.

Now I want to run some basic statistics against my array, for example:
For hour 14, what was the average percent of all values within that hour?
Application.worksheetfunction.average(MyArray,1,14)

Based on my different (random) attempts at syntax, I always get an error
about the number of dimensions, or a type mismatch error. I'v tried various
combinations of commas, parans, etc, but no joy.

Can anyone help me with the syntax to get this first calculation? From that,
I should be able to deduce the syntax pattern and do all the rest.

Thank you,
Keith

Well, one issue is that you dimmed the 3rd parameter from 1 to 12 yet are
referring to 14 in your function, which doesn't exist!

I was trying to indicate that for parameter 1, use the value of 1; for
parameter 2 use the value of 14 (of 24 hours, e.g. 2pm), and I left the third
parameter blank because I wanted my average to include all 5-min increments
within the first two conditions.

Like I said, the syntax eludes me...

I think you'll have to loop through the array.

If the array were just two dimensions, you could have excel help you by using
application.index.

But since =index() only allows 2 dimensions, I think you're stuck
adding/counting within the loop.
