Difference between actual start and actual completion date of task

[sunidala]

Hi,

I am trying to see the no of days between a task's actual completion vs actual start. I wrote the query like this. But it is not giving me any result.

displayname=Difference
textmode=true
valueexpression=WEEKDAYDIFF({actualCompletionDate},{actualStartDate}) valueformat=HTML

Were you able to get this resolved?  I'm trying to do the same thing.  I am looking to have a column that will give me the number of days and time between the actual start date of a task and the actual completion date.  Text mode and I don't get along all the time so if someone has the actual code i can copy and paste that would be amaizing.
