Andy,

Try

=IF(SUMPRODUCT((A2:A101="")*(A3:A102<"")*(A1:A100 <""))0,"Coding error","All OK")

Note the slight offsets of the ranges...

Does anyone know a simple way to count the number of blank cells between
non-blank cells? I have a column of data that in some cases has from zero to
five blank cells between non-blank ones. If there are not two blank cells
between the non-blank ones, it is an indication of a potential coding error
within the data source. I'm looking for an easy way to do my data scrub.

Any ideas would be helpful.

Thanks.
