Since the logic behind this line of data is rather convoluted (That field calculates the a carried-forward # of hours between your volunteer start date and the start date of the report. If my year starts 1/1 and my report is for Jan 1 - March 31, it won't count the total for the year, it will report 0.00. If my report start date is 3/1 - 3/31, that line will total the volunteer's hours between 1/1 and 2/28.)
What volunteer manager thinks like this or wants this breakout. It's very confusing to have someone volunteer 10 or 12 times and see the "total since the start of the year" be 0.00.
Give us the option in Report Options to NOT include this line on the report.
