In a ssrs 2008 r2 report, I have found the following expression and I would like you to explain the following code to me:

=IIF(Lookup(Fields!SK.Value, Fields!SK.Value, Fields!StCount.Value, "DS_StCount") = Nothing, 0, Lookup(Fields!SK.Value, Fields!SK.Value, Fields!StCount.Value, "DS_StCount"))

I know that a lookup function compares the first values to see if they are equal, and if so they value in the third column is returned. However I do not know what this enire
iif statement is doing. Can you explain it to me?

it checks if the value SK has a valid match in dataset DS_StCount if yes it will return the StCount of the first matching row. otherwise it will return 0. IIF is like CASE WHEN. It checks for a condition and returns two return value one for true part and another for false.
