I have a group of individuals, and I need to sum 90 days out from each particular date, so that I can find whether or not they ever met a certain threshold within a 90 day period.

For example if I have this table:

ID Amount       Date

1  2               1/12/15

1  4               1/30/15

1  6               3/2/15

2  8               1/18/15

2  10               1/20/15

2  12               1/28/15

2  14               2/10/15

2  16               2/12/15

2  18               2/25/15

2  20               3/4/15

2  22               4/1/15

2  24               5/22/15

2  26               5/27/15

2  28               6/3/15

2  30              6/6/15

3  32               1/12/15

3  34               6/12/15

I want these results:

ID Amount       Date      SUM

1  2               1/12/15     12

1  4               1/30/15     10

1  6               3/2/15        6

2  8               1/18/15     120

2  10               1/20/15   112

2  12               1/28/15   102

2  14               2/10/15   90

2  16               2/12/15   76

2  18               2/25/15   84

2  20               3/4/15    90

2  22               4/1/15    130

2  24               5/22/15   108

2  26               5/27/15    84

2  28               6/3/15       58

2  30              6/6/15       30

3  32               1/12/15     32

3  34               6/12/15     34


And if my threshold were 115, Person 2 would have met that requirement but Persons 1 and 3 would not have.

Hopefully this makes sense to everyone. I was thinking of using a DO WHILE loop, but I'm not sure whether or not that would work here. Any help would be greatly appreciated.

Thanks!
