Excel 2003 has COUNTIF and SUMIF functions, but not COUNTIFS, AVERAGEIF, AVERAGEIFS, or SUMIFS. You could use array formulas, or SUMPRODUCT formulas like the following: in A2 (count formula): =SUMPRODUCT(--(I2:I65000>0),--(I2:I65000<0.0416667),--(Q2:Q65000=W7)) in A1 (average formula): =IF(A2=0,0,SUMPRODUCT(--(I2:I65000>0),--(I2:I65000<0.0416667),--(Q2:Q65000=W7),U2:U65000)/A2) Please note that you can't use whole columns with SUMPRODUCT in Excel 2003.

If not, what are my alternatives to writing formulas to look at multiple columns and do average and count functions? A suggested possible solution was to buy Office 2007, write the formulas in that sheet and then "down convert" the formulas to 2003. Does anyone know if this actually works? I will give an example to help. I have a sheet with ~40,000 lines of data. Columns are: 1. Day of week (formula from a date/time field of when blood was drawn) 2. Time of day (formula from same field in #1) 3. Turn around time (formula from date/time of blood drawn until results available to clinician from another captured date/time) What I would like is an average for #3, given hour of day blood drawn (#2) and day of week (#1). My friend and I have come up with these 2 formulas in Excel 2007 for average turn around time and counts for # of blood draws for each hour of the day for our inpatients: Average TAT: =AVERAGEIFS(U:U,I:I,">0",I:I,"<.0416667",Q:Q,"=Fr") this is the formula for midnight to 1:00 AM Counting: =COUNTIFS(I:I,">0",I:I,"<=.041667",Q:Q,W7) where W7 is the cell that has "Fr" for Friday, etc... I had asked a question of this group earlier and was given an answer of using conditional array formulas which worked beautifully. It was noted by the person that you cannot use I:I for complex formulas in 2003 but you can in 2007 so I did modify the formula everywhere there was a colon I entered numbers for the cells and it still gives me "?NAME" for an answer. Formula I used was : =AVERAGEIFS(U2:U60000,I2:I60000,">0",I2:I60000,"<.041667",Q2:Q60000,="Fr") hoping that adding the numbers would solve the problem....it doesn't. Any help or additional information about 2003, 2007, compatibility, AVERAGEIFS, etc... would be greatly appreciated. I hope everyone has a great Thanksgiving.
