i have this formula to print multiple parameters in the header and it works :
WhilePrintingRecords;
StringVar Array Input := {?param};
NumberVar howmany:= count (Input);
if howmany > 0 then ', ' + Input [1] +
if howmany > 2 then ', *****'
my problem is when the parameter has no value (it means all records) the report stop with the error “Parameter has no value”.
in that case i want to print blank field or ‘ALL RECORDS’
do you know how ?
thanks
