Declare variable to pass sub-report report total to main

[CLogix]

How would I declare a variable to pass the report total of a sub-report to the main report? In the sub-report I declared:

whileprintingrecords;
numbervar Total := sum({@Labor});

In the main report I called:
whileprintingrecords;
numbervar Total

This did not work.

Add the word Shared at the start of the cdeclaraion:

whileprintingrecords;
Shared numbervar Total := sum({@Labor});

In the main report:
whileprintingrecords;
Shared numbervar Total
