Problem displaying balance accumulator

[chinkums]

I am trying to read a file and display data. The data is bank transactions. I need to display the data from the file with a balance column added at the end keeping an accumulated balance of the deposits/transactions. I am having difficulties with the accumulator.

Additionally it will need to display an NSF when the balance goes below 0. I haven't focused terribly on that and plan to do so once I get the balance accumulator working.

Any help understanding what I am doing wrong would be greatly appreciated!!!

The data file:

02/03/2012 Initial_Deposit         2000
02/04/2012 Swinn_Super_Deluxe      -660
02/06/2012 Swinn_Starlet           -420
02/07/2012 Walmart_Slim            -325
02/10/2012 Swinn_Tabgo_Tandem      -770
02/11/2012 Suwanee_Tango_Tandem    -660
02/13/2012 Deposit                 5000
02/15/2012 Suwanee_Creek_11_Trek   -730
02/20/2012 Cycles_ATL_12_Trek_Cpk  -1210
02/23/2012 Cycles_ATL_11_Trek      -1250
02/24/2012 Kmart_Special           -250
02/25/2012 Deposit                 4000
