As long as the target section is below the section where the subreport is, you can declare and set the value of a shared variable in the subreport.  Then, in a main report formula, declare the same shared variable.  Google "Crystal shared variables" for examples.

Ido is correct.  The biggest mistake report developers make with shared variables is they try to use the shared variables in sections before the subreport.

Crystal evaluates sections from the top down and subreports are the last objects evaluated in a section so the values from the subreport cannot be used until the section after the subreport.

Basic method I use
In the main report
Add a formula to the report header
WhilePrintingRecords;
Shared NumberVar mySharedNumber;
""

Open in new window


In the subreport add a formula
WhilePrintingRecords;
Shared NumberVar mySharedNumber;
mySharedNumber := Formula for the value;
""

Open in new window


In a section after the subreport to display the value
WhilePrintingRecords;
Shared NumberVar mySharedNumber;
mySharedNumber 

Open in new window


The WhilePrintingRecords line is not required.  Using Shared variables forces the evaluation to be in the printing pass.  However, I use it as a way to document when the formula is evaluated.
