I have a report that uses a parameter (Cascase LOV with part_no field as multivalued entry).  My record selection formula is

{DEFECT_CODE_DETAILS_VIEW.PART_NO} = {?PartNo}.

I also have a report header that shows the value of the parameter.  As many of you know if I just put the parameter like {?PartNo} and if I select two parts from LOV for my report, I will only show the first part in report header.  I need a formula to show all the parts in report header and have to have enough space to display it. I read that I have to have a formula that uses an array.  However, I do not know the full syntax of the formula.  I would highly appreciate someone writing th exact formula for me if I select two parts from drop down menu during report execution.

Thanks in advace for all of your help.
