          Formula : 
                                Whileprintingrecords;
                                shared numbervar total;

Cause

When we use a shared variable in a particular section and pass this variable to the main report and display it in the same section, then we find that the variable does not pass the value as a shared variable.

Resolution

To rectify the problem, ie) for the proper functioning of the shared variable we have to follow the below steps..

  1. Declare a variable as shared while writing the formula in a subreport and place the formula in the sub report

  2. Use the same variable in main report which was declared as shared in subreport.

  3. Insert a new section below the sub report and place the main report formula in the new section.

  4. Goto > Section Expert in the main report > Select the sub report section > Select "Underlay Below Section".

  5. Now create a manual running total using that variable.
