If you still have problems, the Google link from my post in the
"Trendline equation in chart is wrong" thread (Nov 2003) should work.

Hi Jerry,
Can you post that link again, for some reason it's truncated and
returns a Not found @ google.

Alternately, David Braden has posted VBA code to extract the
coefficients directly from the chart into cells

The advantage of using the chart coefficients (either manually or via
Braden's code) is that LINEST (prior to Excel 2003) uses a
numerically poor algorithm that can give inaccurate results with some
data sets. The chart trendline (extracted by Braden's code) is much
better numerically.
