Hi -

I'm performing a shopping cart analysis (if customers purchase product
A what else do they also purchase?) and have run into a bit of a
snag ...

I need a procedure that will return the most frequently occurring text
string found in a contiguous block of 4784 cells (A1:AT104). There
are over 10,000 possible values that could be in these cells, so
counting the occurrence of ALL of them wouldn't be that efficient ...

Additionally, a significant number of the cells in the target block
could contain the value 'end' or '#N/A' -- these values need to be
ignored.

Ideally, the solution would be scalable (allow users to select larger
or smaller range) and also allow for choosing the Most frequent, 2nd
most frequent, 3rd most frequent, etc values. So, something like:
=UDFname(range,3) would return the 3rd most frequently occurring text
string in the specified range.

Any ideas of how to do such a thing? The only solutions I could find
required either knowing what string value to look for or returning a
list of values (sorted one way or another).

Thanks for looking!
