I am looking for some help. I have 2 columns: 1 with a date, and 1 with a score. I am looking to show monthly averages automatically. Here is an example:
Date Score Month Average
20-Jan-12 91.6 January
12-Jul-12 99.6 February
23-Feb-12 88.8 March
23-Feb-12 88.0 April
23-Feb-12 92 May
24-Feb-12 87.0 June
17-May-12 98.0 July
18-May-12 92.0 August
19-May-12 90.0 September
20-May-12 93.0 October
27-Jan-12 99.2 November
28-Jan-12 85.0 December
29-Jan-12 77.0
30-Jan-12 65.0
1-Feb-12 98
2-Feb-12 97.0
4-Jan-12 98.8
12-Dec-12 100.0

Any suggestions?
Thanks
