Dynamic number of columns where value is greatert than 0

Hi,
I'm trying to name a dynamic range using Offset.

=OFFSET(Cumulative!$C$4,0,0,COUNTA(Cumulative!$C4:$BB4),COUNTA(Cumulative!$C$4:$BB$4))

When I test the range the "dancing ants" cover the wrong area so I've obviously not grasped the concept of the Offset function.

I also cannot get it to work at all if I add the ">0"

What I'm trying to achieve is to have the named range expand to cells that have a value greater than 0 in row 4 from column C to column BB.

If I can get my head around this, I can alter the formula for more ranges and build a dynamic chart.

I have added a flat file so you can see what I'm trying  to work with.

As always your time is appreciated

Managed to get it to show the correct row now, but cannot fathom how to only expand to include cells greater than 0.

=OFFSET(Cumulative!$C$4,0,0,COUNTA(Cumulative!$C4:$C4),COUNTA(Cumulative!$C$4:$BB$4))

try this

=Sheet1!$C$4&":"&(CELL("address",INDEX(Sheet1!4:4,MATCH(0,Sheet1!4:4,0)-1)))

Open in new window

Hmmmm,
"try this" ..... where?
In a cell, or in the offset formula?
I tried in the offset formula but couldn't get it to show the correct data.

I also tried it in the Name Manager and changed "Sheet1! to the correct name (Cumulative), but still no joy.
:(

Yes.
The named range is

=OFFSET(Cumulative!$C$4,0,0,COUNTA(Cumulative!$C4:$C4),COUNTA(Cumulative!$C$4:$BB$4))

C4 always has a value greater than 0, but the columns grow as weeks are added, so I am trying to get the named range to expand to only cells in row 4 where the value is greater than 0

I was thinking that maybe I could put a formula in an unused cell to return the cell address of the last cell in row 4 where the value is greater than 0 and refer to that in the named range "Offset" clause, but I can't get it to work.

ok if this is what you want then do this
=CELL("address",INDEX(Sheet1!4:4,MATCH(0,Sheet1!4:4,0)-1))

this will give you the last cell that contain non zero in row 4 starting from C4

Thanks,
I have entered that formula into an empty cell ( T1 ), and tried to refer to that cell in the offset formula of the named range,
=OFFSET(Sheet1!$C$4,0,0,COUNTA(Sheet1!$C:$C),COUNTA(Sheet1!$C$4 & ":T1 &"))

But I can't seem to refer to the cell address that T1 shows, (incidently currently I4)

pls post what you did as the file you posted did not have the offset formula so I was lost in what your trying to achieve. I usually solve things quickly !!!

Hmmm.
I'm trying to do what I said earlier at http://www.experts-exchange.com/Software/Office_Productivity/Office_Suites/MS_Office/Excel/Q_28371615.html#a39879408.
The Offset is in the name manager? And its called Total509Builds?

I now have this as the named range...
=OFFSET(Toyota!$C$4,0,(Toyota!T1),COUNTA(Toyota!$C4:$C4),COUNTA(Toyota!$C$4:$BB$4))

on the sheet ("Toyota") at cell T1, is the formula to get the cell address of the last cell in row 4 which is greater than 0.... "=CELL("address",INDEX(4:4,MATCH(0,4:4,0)-1))" , which returns the value $I$4.

I still can't get the offset range to show C4 to the variable cell address value of T1

Here it is, I finally got it !!!
=Toyota!$C$4:INDEX(Toyota!$4:$4,,MATCH(0,Toyota!$4:$4,0)-1)

I create it in your last file and updated both
Total509Builds  I put its SUM in Cell G1
Total519Builds  I put its SUM in Cell H1

Just put any value in any 0 column in row 4 or row 21 and see how it automatically update G1 and H1.

Enjoy
