I have a very lengthy column which includes data of various sorts: some cells
are textual, some have dates, and others are numbers. I need to add the
values in only the cells that have numbers. The SUM formula disregards text,
so those cells don't pose a problem, but the date cells skew my results if I
use some (since they get included in their converted representation).

Is there an easy way to add only numerical (ie, non-date and non-textual)
values?

On a similar note: Is there a quick way to count the cells that have text in
them? I don't need a sum in this case: Just a count of the cells.

Thanks!
