In your sub report create a formula to pass teh values to the variables i.e.
//@SubRptData
WhilePrintingRecords;
Shared StringVar JobNum := {My Job Number}; ''change to Numbervar if a number is required here
Shared StringVar Desription := {My Description}
Then in the main report create formulas to display the data from the sub report i.e.
//@JobNo
WhilePrintingRecords;
Shared StringVar JobNum;
//@Description
WhilePrintingRecords;
Shared StringVar Description;
These can then be placed on the main report to diplay the sub report data, bearing in mind they must placed in a section after the section containing the sub report.
