I think the formula for "Wanted Cash" can be one of the following
(assuming the first -63000 line is row 3 and "Wanted Cash" is column
C):

C3: =IF(A3<0, SUM($A$3:A3), C2)

C3: =if(A3<0, B3, C2)

Copy down column C as needed. The first formula allows you to avoid
the "Balance" column. But since I suspect the "Balance" column is
useful to you, the second formula is the more efficient and
straight-forward, IMHO.
