I'm on Windows 7 (64bit) using Office 2010.

Question One:
I have a set of journal titles which people have used, and the format is as follows (this is an excerpt of some 400 entries)

Sedimentology
Sedimentology
Sedimentology
Sedimentology
Senckenbergiana Maritima
Tellus A
Terra Nova
Terra Nova
Trudy Instituta Okanologii
Vie et Milieu
Polar Biology
Polar Biology
Polar Biology
Marine Biology
Marine Biology
Ophelia

How do I could the number of times Polar Biology (as an example) was used? Bearing in mind that some journals have been used 20-30 times, so counting is a very last resort!

Question Two:
In another excel spreadsheet I have a list of single digits and digit ranges. eg.
1-4
5
6
7-12
13
14-19
etc
How do I format the cells so the ranges don't turn into dates? If I change all cells into text I get a huge list of errors.

Thanks in advance for any help.
