title: SSRS 2008 help. What is a data scope
body: <p>I am working with ssrs 2008. I am using this expression <code>=Sum(IiF(Fields!RegisterID.Value=6000,1,0)</code> and <code>if(Fields!PointID.Value=500,1,0))/Sum(Iif(Fields!PointID.Value=500,1,0))</code> when I go to run it I get this error message The Value expression for the text box ‘Textbox1’ uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one data set. What do i need to do to fix this? Thanks in advance!</p>
