Hi,

I've been working with dynamic named ranges, charts and pivot tables.
They seem to work fine, as long as the source and chart are in the same
file. When they are in different files, I'm getting "Your formula
contains invalid external reference to a worksheet".

The data is horizontal, a la "Jan Feb Mar" with me adding new columns
to the right and capturing the last 12 mths.

When I have the ranges defined in the source file, I can click in the
Refers to field and it puts the marquee around the correct range. I can
also hit <F5 and put the range name in there and the correct range
gets selected.

However, when I click the series in the chart and try to put the range
names into the series formula, I get the error above.

The original series formula is
=SERIES('[05-CSAT-Tracker.xls]FIN_Months'!$AI$7:$AT$7,'[05-CSAT-Tracker.xls]FIN_Months'!$AI$7:$AT$7,'[05-CSAT-Tracker.xls]FIN_Months'!$AI$8:$AT$8,1)

The named ranges look like:
Name: Months_RecCallOverallLabels:
Refers to:
=OFFSET(FIN_Months!$AA$7,0,COUNTA(FIN_Months!$AB$7 :$IV$7)-11,1,12)

Name: Months_RecCallOverallBot:
Refers to:
=OFFSET(FIN_Months!$AA$7,1,COUNTA(FIN_Months!$AB$7 :$IV$7)-11,1,12)

With the range names, it looks like:
=SERIES(Months_RecCallOverallLabels,Months_RecCall OverallLabels,Months_RecCallOverallBot,1)

I've tried it with and without replacing the name_ref argument.

I've tried it without the file references (although it escapes me how
they would find each other without that).

I've even tried defining the named ranged in the target file, hoping
the file name would allow that to work. Argh.

What am I missing?

Thanks!
