Hi,
how do i collect / use querystring parameters to include within a filter on a DV that is based over a DF instance?
so if in the url for the page with the DV I have a querystring parameter of Userid=1, how do i filter the list to display in the DV to only display records where the UserID column is equal to 1, the value passed in as a querystring parameter?
I'm guessing I use the filter option, but don't no how to refer to the querystring parameter in the below:

Help would be greatly appreciated.
Cheers
Tony
