Value match within date range
Hi All
Could anyone help wih this formula calculation i am trying to establish whether a machine that i refurbished (has a 12 month warranty) has failed (been returned to me and logged) during that warranty period, the data i have to work with is the serial number of the equipment plus the date it was refurbished. Therefore i would like to perform a serial number match over the last 12 months per month as all equipment is returned to me for repair. Data i have is: "With costs" worksheet, "Serial no" column and "Date" of the refurb column (among others, but i figure i will only need these two columns for the calculation) The sheet i want to put the data onto has the 12 months of the year Jan - Dec ("Monthly") so that i can see how many failures during Jan how many during Feb etc Hopefully someone can understand my bad explanation :) Many thanks Derek |

Assuming that your dates are in column D of the With costs sheet,
occupying rows 1 to 18 (used in my test - adjust to suit your data), and that your months are the first 3 characters of the month in A2:A13 of your monthly sheet, put this formula in B2 and copy down: =SUMPRODUCT(--(TEXT('With costs'!D$2:D$18,"mmm")=A2)) If you use the full month name, then add a fourth "m" to "mmm". Hope this helps.

Value match within date range
Hi Pete
That works a treat, but what i really need is the serial number match i.e. a particular machine serial number comes back to me, i put that in the coloumn and it looks for a match over the previous 12 months to see if it has been back before i.e under my warranty, sorry about my dodgy explanation Thanks Derek "Pete_UK" wrote: Assuming that your dates are in column D of the With costs sheet, occupying rows 1 to 18 (used in my test - adjust to suit your data), and that your months are the first 3 characters of the month in A2:A13 of your monthly sheet, put this formula in B2 and copy down: =SUMPRODUCT(--(TEXT('With costs'!D$2:D$18,"mmm")=A2)) If you use the full month name, then add a fourth "m" to "mmm".
