Adding an OR to SUM(IF....
=SUM(IF(MONTH($A7)=MONTH(DTd)*IF(DTam="M",1,0),DTe b),IF(MONTH($A7)=MONTH(DTd)*IF(DTam="A",1,0),DTeb) ) I would like to combine if possible to read something like this? Doable? =SUM(IF(MONTH($A7)=MONTH(DTd)*IF(OR(IF(DTam="M",1, 0),IF(DTam="A",1,0)),DTeb))) I can't seem to get the OR to work? Basically I am trying to simplify the formula. Let me know if I need to clarrify this any further? -- JustMe602 ------------------------------------------------------------------------ JustMe602's Profile: http://www.excelforum.com/member.php...o&userid=27854 View this thread: http://www.excelforum.com/showthread...hreadid=498002 |

Adding an OR to SUM(IF....
Hi!
Try this (not an array, normally entered): =SUMPRODUCT(--(MONTH(DTd)=MONTH($A7)),--(ISNUMBER(MATCH(DTam,{"M","A"},0))),DTeb) Biff "JustMe602" wrote in message ... =SUM(IF(MONTH($A7)=MONTH(DTd)*IF(DTam="M",1,0),DTe b),IF(MONTH($A7)=MONTH(DTd)*IF(DTam="A",1,0),DTeb) ) I would like to combine if possible to read something like this?

Adding an OR to SUM(IF....
Okay thanks for the reply it but I am confused on the syntax. And how and why it worked. =SUMPRODUCT(--(MONTH($A7)=MONTH(DTd2006)),--(ISNUMBER(MATCH(DTam2006,{"M","A"},0))),DTeb2006) What does the "--" two dashes do? I guess I really don't understand how the SUMPRODUCT works. Before the first comma, for instance, this matches where the two columns/ranges equal the same month. Then the ISNUMBER(MATCH... this section looks for intances where DTam2006 equals "M" or "A" then brings back the information in the range DTeb2006. But why without an if statement? Please if anyone could help explain this it would be greatly appriciated and again thanks for the formula.

Hi!
The formula is operating on 3 arrays: DTd2006 DTam2006 DTeb2006 On the first 2 arrays you're performing a logical test: MONTH($A7)=MONTH(DTd2006) ISNUMBER(MATCH(DTam,{"M","A"},0) The results of those tests will return the logical values of either TRUE or FALSE. The "--" converts those to numeric values where TRUE = 1 and FALSE = 0. Then all 3 arrays are multiplied together and then the results of the multiplication are summed together to get the final result. It would look like this: 1*1*10 = 10 1*0*12 = 0 0*0*15 = 0 0*1*10 = 0 1*1*20 = 20 result = 30 See: http://www.xldynamic.com/source/xld.SUMPRODUCT.html Biff "JustMe602" wrote in message ...
