Reset Formula for Each Group

I am trying to build a report where I concatenate a buch of email addresses, but I can not figure out how to reset the var on each group change. Can any one help Please
WhileReadingRecords;
Global stringVar VEmail;
 
// need code to reset VEmail on the change of each group. 
 
VEmail := VEmail & {sql_Group.Contact Email} & "; ";
 
VEmail & "Smith@Smith.com";

Open in new window

In the group header use another formula field:

//@reset
Global stringVar VEmail:="";
""

I think I would be surprised if you could do this
 'whilereadingrecords'

I would have expected 'WhilePrintingRecords'
in both formula fields.
