From: nadesico on 3 Jun 2010 23:02 I have three fields in a table, and want to determine the total of the occurrences by a certain time period. The data I have looks like this. FGC RDate Occurrences 81 2009/01 1 81 2009/02 1 81 2009/03 1 81 2009/04 1 81 2009/05 5 81 2009/06 84 81 2009/07 1 81 2009/08 6 81 2009/09 3 81 2009/10 1 81 2009/11 5 And I want it to look like this FGC 81 Less Than 3 Months 9 3 Or More Months 91 6 Or More Months 7 9 Or More Months 2 12 Or More Months 0 The month that the results are based off of is 2009/11. For this example, I am using a specific month, but for future use the month will be determined by Date() converted to yyyy/mm. Any help would be greatly appreciated. Thanks From: PieterLinden via AccessMonster.com on 3 Jun 2010 23:58 First off, you have to use DateDiff() to determine the number of time units between the two dates. e.g. DateDiff("q", FirstDate, SecondDate) will return the number of quarters between FirstDate and SecondDate. Then you can use switch to nadesico wrote:>I have three fields in a table, and want to determine the total of the >occurrences by a certain time period.
