Answer 1

You need to add the scope. Then the runnung value will be calculated on the whole dataset or based on your grouping. For example:

=RunningValue(Fields!ItemId.Value, Count, "YourDatasetName")

=RunningValue(Fields!ItemId.Value, Count, "YourGroupName")

This gives you two different results based on the scope. And you need the second one I think.
