I have been able to get the correct Sum that I needed.  I didnt use the complete Solution DBlank provided. I did not need the first Running Total and I had to add more to the formula in the  2nd Running Total.  In the formula I had to include Previous(fileID) <> FileID.  So the formula on the Running total distinct count of FileID is

(Isnull({vw_MF_All_2010_Liable_Files.Amount}) or {vw_MF_All_2010_Liable_Files.Amount} = 0.00) and
previous({vw_MF_All_2010_Liable_Files.FileID}) <> {vw_MF_All_2010_Liable_Files.FileID}

Using just the first part of this formula counted even those FileID's where there were more than one row for that FileID.  I did not need to use the first running total. 

I created one formula called Sum of 0.00 trans that took the Running Total count * 600.

Then the final Sum formula was this
{@Sum of 0.00 Trans} + Sum ({vw_MF_All_2010_Liable_Files.Amount})

Without your insight and Assistance DBlank I might never have come up with the final solution.  You got me headed in the right direction and I really appreciate that help.
