I'm working on drill down functionality in SSRS report with reference to tututial given at http://ssrs2008.blogspot.in/2010/09/creating-drill-down-report-with-sql.html
But I'm getting error
Toggle items must be textboxes that share the same scope as the hidden item or are in a scope that contains the hidden item , and cannot be contained within the current report item unless current grouping scope has a Parent.
How can i overcome this issue? Please suggest.
