Today() - Job_Status_Change__c

Here is an example of what my formula is producing for a Job that has on it's 50th day:

Stage 1 50

Stage 2 50

Stage 3 50

Stage 4 50

Stage 5 50

Here is what that very same project Stage Duration will reflect should I create the correct formula:

Stage 1 5

Stage 2 9

Stage 3 4

Stage 4 12

Stage 5 19

* the aggregate days for this Job is still 50 days, but the formula has captured the total number of days this Job sat at each of our Stages. 

Any suggestions?

Thanks in advance for you help.
