FDM FDMEE Jython Import Script Error - excel .csv tab delimited

Thanks in Advance for looking/sharing - your consideration is certainly appreciated.

Can anyone provide a suggestion as to how best fix this failure?

I need a simple script to look at the last character of the 2nd column (Account) and determine if it is an ' @ ' symbol.

If yes, then multiply the value in the 6th column by -100 and return the record with the calculation performed.

Otherwise, return the record without the calculation.

(( Ideally, any Negative Value in END-BAL (column 6) Less than 0 and Greater Than -1 would return a Positive Whole Number  e.g. -.17 would return 17 ))
