I would like to find out,if it is possilbe to create a fomulate that will do :

I enter project names in a row (day name) that has a corresponding column (a
15min timeslot)

11:00 11:15 11:30 11:45 12:00 ....
Monday Alpha Beta Omega Alpha Delta
Tuesday Beta Beta Alpha ....
...

I would like to have the project displayed (in a separate result cell) that
occurs the most, hower I would like not to have a numerical value as a result
- I would like to have the porject name displayed. Furthermore in an another
result cell I would like to have the time calculated that I spent working on
that project (my 15 min.time slots).

Is it possible to design such a function without doing a UDF?
Kind Regards for all suggestions or recommendations.
