Hi Rich,

How could we possibly know if you don't give us:

Values input to the formulas,
The formulas,
The results of the formulas,
What you expected,
What the eyeball expectations were
?

Kind regards,

I am trying to calculate values for a curve using the LOGEST fx, but the
numbers are not agreeing with the formula provided by the logarithmic
curve
formulas in a chart of the data (nor by the 'eyeball' method). Any
thoughts?
