Hello,
I am working again on something that is a little to tricky for me and seems to be the right thing for a good start into the weekend. 
This time I need some help with a formula.
What I like to achieve:
| ID | Status | Time | needed time total |
| 1 | new | 01.01. | |
| 1 | progress | 02.01. | |
| 1 | solved | 03.01. | 2 days |
| 2 | new | 02.01. | |
| 2 | solved | 08.01. | 6 days |
If the status for an ID is solved then it should search for the same ID with status "new" and calculate the total time that was needed to solve the ID.
Any ideas? Maybe to steps calculation? first provide the right time and in the next step calculate the TimeDiff? Major problem here is that I don't know how to get the time out of the line with the same ID (status) "new" in a new field.
thanks for reading it.
