## Loading Previous Data

Hello,

What I am trying to accomplish is to sum all amounts for each year based on field 1 and field 2, but if a year has no amount, to use the previous one that is available.

Field1,Field2,Field3,Amount

1,B,2015,50

1,L,2015,75

1,B,2016,0

1,L,2016,0

1,B,2017,100

1,L,2017,125

2,B,2015,90

2,L,2015,120

2,B,2016,0

2,L,2016,0

2,B,2017,0

2,L,2017,0

3,B,2015,90

3,L,2015,120

3,B,2016,40

3,L,2016,80
