[Sovled] Question Count fomula?

Hello,

I have been using this formula

=COUNTIF(Master!I:I,'Source Lists'!A1) It is counting trends for the year, in a summary tab. (this works)

(Master is a tab with all the daily information for incidents, The Source list is a seprate tab where I put my pull down menu information, and this is going in a thrid tab called trends. )

The "master" tab has a date column 01/11/12 format I would like to set up the summry tab by month is there a way to add that to this formula?

Currently the trend tab/sheet looks like this

......................Total
MUI - Verbal ......5
MUI - Physical.....0
MUI - ***...........0


I want to track trends monthly and quarterly

...................... Jan.... Feb ...March .... Total
MUI - Verbal........2.....3........0
MUI - Physical .....0.....0........0
MUI - *** ...........0.....0.......0

I hope I have given enough inoformation, Thank you, Excel 2010
