Find Specific withdraw entries from Bank Statements

hi,

I use online banking for paying my monthly bills. I get different confirmartion for each pay transection. Pls look attached Excel file. Now I want to find specific bills expense with amount from all my 12 months bank statements. How can I get this task done.

Note: Each time get different confirmation which appears on my bank statement beside paid bill name. for example January 2009 statement GAS Z8A.... Feb 2009 GAS S2W. I hope this clarify. What I have to do if I want to get all my 12 months GAS money withdraw from bank statement. I use csv file for bank statement.

Thanks
GP
