hi Pardib this my sampl Data i used your Expression it works but my request is i need to show a table that calculate the amount in max date VS the amount in the Previous date right before it here is my example:
| ID | Balance | Date |
| 07019 | 20994.09 | 3/19/2015 |
| 07019 | 21035.58 | 11/26/2014 |
| 07019 | 21077.07 | 12/31/2013 |
| 07019 | 20007 | 1/31/2014 |
| 07019 | 17000 | 2/28/2014 |
| 07019 | 18000 | 4/30/2014 |
| 07019 | 12000 | 5/31/2014 |
| 07019 | 10000 | 6/30/2014 |
| 07019 | 14000 | 7/31/2014 |
| 07019 | 25000 | 8/31/2014 |
| 07019 | 55000 | 9/25/2014 |
| 07019 | 153000 | 10/17/2014 |
| 00534 | 144551 | 3/19/2015 |
| 00534 | 153420 | 11/26/2014 |
| 00534 | 161708 | 12/31/2013 |
| 00534 | 25000 | 1/31/2014 |
| 00534 | 26000 | 2/28/2014 |
| 00534 | 29000 | 4/30/2014 |
| 00534 | 35000 | 5/31/2014 |
| 00534 | 45000 | 6/30/2014 |
| 00534 | 26000 | 7/31/2014 |
| 00534 | 29000 | 8/31/2014 |
| 00534 | 22000 | 9/25/2014 |
| 00534 | 21000 | 10/17/2014 |
in this Case i need my output will show if no selection on any field the Amount on max date VS the previous one in my example :
ID MaxDate (3/19/2015) PreviousDate(11/26/2014) Lost Amount
07019 20994.09 21035.58 20994.09-21035.58=(41.49)
00534 144551 153420 153420-144551=8869
if i select on for example 10/17/2014 i get
ID MaxDate (10/17/2014) PreviousDate(9/25/2014) Lost Amount
07019 153000 55000 153000 - 55000=98000
00534 21000 22000 21000-22000 =(1000)
