Hi wizards
I have a workbook with sheets for each month. The 13th sheet is for the year totals. I would like to average the totals for the months on a rolling basis. for example add jan,feb,march etc then divide by the number of months. I have tried =sum(jan!e18:dec!e18)/counta(jan!e18:dec!e18) which divides by 12 but if it is only august then I need it to divide by 9. Also when I put the range in as an array it won't work as the cells I am taking my info from contain a formula and unticking "show zeros" has no effect. Hope you can help |
