Geoff, If the formula you were using in the conditional formating function gives you the correct answer in the first cell then you just have to put some changes on it. <=(COUNTIF($AC$3:$AC$500,"*"))*0.05 putting the dollar cell on the cell reference makes the cell an absolute field, that if you move or copy the formula it will still refer to that cell range. with that formula you will have to change the "0.05" for your other criteria. You can also try this formula, to meet your 1st criteria of top 5% IF((RANK(AC3,$AC$3:$AC$500))<(0.051*(COUNT($AC$3:$AC$500))),1,0) to meet you 2nd criteria of 5% - 20% IF((RANK(AC3,$AC$3:$AC$500))<(0.21*(COUNT($AC$3:$AC$500))),1,0) to meet you 3rd criteria of 20% - 50% IF((RANK(AC3,$AC$3:$AC$500))<(0.51*(COUNT($AC$3:$AC$500))),1,0) Vergel ----- Original Message ---- From: Jim Hickey <jim@xxxxxxxxxxx> To: mso@xxxxxxxxxxxxx Sent: Wednesday, September 12, 2007 7:53:57 PM Subject: [mso] Re: Conditional format of %range of column Geoff, I would use something like this =3DIF(RANK(A3,Ac$3:Ac$500,1)/COUNT(Ac$3:Ac$500)>=3D0.05,1,0) Obviously changing where appropriate. Start with that. Jim -----Original Message----- From: mso-bounce@xxxxxxxxxxxxx [mailto:mso-bounce@xxxxxxxxxxxxx] On = Behalf Of Geoff Culbertson Sent: Tuesday, September 11, 2007 4:15 PM To: Mso Subject: [mso] Conditional format of %range of column In an Excel worksheet I have a column of numbers which have been sorted = with the highest at the top. I now want to identify and conditionally format = the top 5%, then between 5% and 20%, then between 20% and 50%. I have tried using the formula <=3D(COUNTIF(AC3:AC500,"*"))*0.05 in conditional = format but it doesn't work.=20 It works perfectly in a cell, so maybe I will have to have an additional column which I can hide, but refer to in the conditional format menu. Any other ideas?
