Multiple Sheets with Data

Hi I have a spreadsheet with 8 clients listed on 8 rows. There are 9 coulmns of information. I have the following formula at the very bottom of the sheet (=SUMIF($D$5:$D$96,I113,$C$5:$C$96). I want to be able to move this formula to a separate sheet kind of like a summary sheet and have information from multiple sheets "drop in" here. I hope that makes sense.
