I want to create a dynamic variable, let's call it vInput and use it to compare with a loaded field, say Var%. If vInput>Var%, I want the sum of all the records satisfying this condition in another field, call it 'Benefits'. Also, I'd like to be able to change the dynamic variable vInput from within the dashboard using the Variable extension or any such option such that my charts respond to this variable changes. Some one tell me how to do this. Thanks in advance.
