Counting dates that do and do not match

[OTT]

I have the following columns in my spreadsheet:

M = Date of Interim Reply
X = Date of Final reply
C10 = Start Date
C11 = End Date

I want to count the number of responses that have been issued during a certain period of time which I enter into C10 and C11 i.e. 01/05/2011 to 31/05/2011.

Not everything receives both an interim and final response. If only a final response is issued, there is a formula in Column M which will copy the date from Column X - we have to do this to record that the case has been closed.

In order to calculate an accurate number of responses issued I think I would like two formulas.

Formula 1 - I would like this to calculate the number of entries in Column M and Column X that fall between the start and end dates where the date entereed in these 2 columns is the same.

Formula 2 - I would like this to calculate the number of entries in Column M and Column X that fall between the start and end dates where the date entered in these 2 columns do not match.

Can anyone help me with this please?
