Multi Parameter and display list

Printed From: Crystal Reports Book — Forum Name: Talk with the Author

Hi,
 
I am using Crystal Xi and and have input two parameters that are both multiple select and i want to list the values in my report in the header - which is fine.
 
i have separate tables that have converted codes in ,which is what i want to bring through on my report headers display.  so to do this i am trying to insert subreports with the formula inserted in the footer:
My user subreport:
whilereadingrecords;

Global stringvar CalcUser;

if instr(CalcUser,{VUserList.User_DisplayName})=0 then

CalcUser:= CalcUser& IIF (CalcUser="", "", ", ")&{vUserList.User_DisplayName};

which works for  user subreport ..  when i do the same for my second subreport  - office subreport the data in the header field goes blank.
 
Urgent - please help!
