#### How do I ignore blank cells while averaging the solutions of equat

```I'm trying to average (items produced/manhours/workers) over the course of a
week.  The problem is each job isnt worked every day, so I have blank cells
in my equation.  Here is what I'm typing:

=AVERAGE((B4/C4/D4),(E4/F4/G4),(H4/I4/J4),(K4/L4/M4),(N4/O4/P4)).

I know there is a way to ignore #DIV/0 results, but I'm fairly new to Excel.
I'm also trying to keep this all in one row to save space.  Any help will be
appreciated.

```I can't get this done without adding another row, but you can always hide the
extra row.
With your data in B4:P4 arranged Items/MH/W, enter these formulas below each
W cell
In D5    =IF(ISERROR(B4/C4/D4),0,B4/C4/D4)
G5        =IF(ISERROR(E4/F4/G4),0,E4/F4/G4)
J5        =IF(ISERROR(H4/I4/J4),0,H4/I4/J4)
M5        =IF(ISERROR(K4/L4/M4),0,K4/L4/M4)
P5        =IF(ISERROR(N4/O4/P4),0,N4/O4/P4)
These replaces the DIV/0 errors with zero and calculate the the daily results
In Q4
=IF(COUNTIF(D5:P5,">0")=5,SUM(D5:P5)/5,(SUM(D5:P5)/COUNTIF(D5:P5,">0")))
This ignores the days with no job and calculates the weekly average based on
the number of days the the work actually happened.
Not pretty, but it works.

Linking cells containing text from one worksheet to a cell with text in another worksheet
I have a workbook with two pages, the first page has cells that contain the main description heading of the cells on the second page. The second page has the heading in one cell and then the breakdown of each section under that, and repeated as there are about 11 sections. When I paste a link or use a hyperlink on the first page, it does take you to the heading cell on the second page, however I was wondering if there is a way to force the cells on the bottom of the page to the top for easier viewing. Right now it just pulls those cells up enough to see them at the bottom of the screen, and ...

Formula to lookup in a range, find duplicates, and then total the data in the applicable duplicate cells in another column
Need to know if the following is possible? I have a worksheet with several columns. One of those columns has some duplicate entries.

Then, based upon the values found in the cells (currency) of a different column in those duplicate rows, total the dollar amounts of these other cells.
