Thanks for all your help "jlclyde" wrote: On Sep 11, 1:34 pm, John Gregory wrote: No it will change as it goes down the list ie B9, B10 and so on and so on, which seems to work fine. I modified it with )*(O2scfm) and it comes back with a #VALUE error. On my 'Data Room' tab I have about 250 rows of information that will contain room name, floor, riser, zone, area type (pull down box), then several cells that I place quantities in, then another similar set of cells which actuall VLOOKUP a range (SCFM) which will return a number which calculated the quantity with the VLOOKUP result and places it in these several cells. I then go back to my Summary Sheet and in cell B8 is Zone 1 which will go all the way down to zone 250. I want the sumproduct to look at 'Room Data' tab to find all zone 1 items and populate this row with the appropriate results under each cell O2, MA, VAC....... This formula I am using is not bringing information from 'Room Data' tab over to Summary sheet from like the 4th row and down. Any ideas would be great.

It does not want to calc the remainder of the range (Zone). I completed about 30 zones on my Room Data tab, and went back to see if it worked, but it did the first few rows correctly then nothing below that, why? Do you want it to always look at B8? If you do then you shoudl put $B $8 instead of B8. I woudl also change your formula to =SUMPRODUCT((Zone=$B$8)*(O2scfm0) * (O2scfm)) but that is just me. Thanks, Jay- Hide quoted text - - Show quoted text - Sumproduct needs to have ranges that are the same size to look at. If your ranges area gettign bigger and your named ranges are not then this is an issue. Either you will have to make your ranges flexible or just put the range into the formula. Jay |
