My dashboard has a "date promt with between criteria". As you know this type of promt has two input areas on screen , one for beginning date second for finish date.
What I like to do is that to pass the finish date to presentation variable. Is it possible to do that and How.?
Anything would really be helpfull.
I know this is a little late for you, but if you are still looking....
Presentation Variables will separate multiple (or two!) values with a comma.
So all you need to do is parse the values pre and post comma, and probably cast it to being a date as it will have been stored as a text value in the presentation variable.
For the first part; -
Hope this is still relevant...
