Hi All,

I have a spreadsheet with an Array entered Formula (based on Rows using
the
TRANSPOSE Function) that produces the #N/A error when no further data is
available to be calculated: this in itself is fine - the #N/A is disguised
with Conditional Formatting. However, if possible, I would like to find
the
AVERAGE of the values in each Row excluding those cells with #N/A from the
calculation.

I've tried a few variations using either the ISERROR or ISNA Function
nested
with the AVERAGE Function. I get either zero or #N/A returned.

The original Formulae providing the results that I now wish to Average was
brilliantly created by Dominic in this previous Post: "Count Intervals of
Filtered TEXT values in Column and Return Count across a Row"

The values returned from the above Formulae is numeric and formatted as
GENERAL.

Thanks
Sam
