A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Please download the 2 files from below links where this has been illustrated:

http://globaliconnect.com/excel/Microsoft/DownloadFiles/Latest_DEBTORS.xls
The formula in Book1.xls file is the same as you have mentioned, only it will not have the $ sign before 8 ie. instead of $A$8 it will be $A8 because the formula is being used for multiple rows.
=IF(ISNUMBER(MATCH([Latest_DEBTORS.xls]sheet1!$A8,Debtors!A:A,0)),"",[Latest_DEBTORS.xls]sheet1!$A8)
