Usage of paramdisplay value when using Multiselect Prompt

[karthik.cognos]

We have a scenario where we need to display more than One value based on the section of prompts.
EX:The prompt page consists of Source Code where the user can select more than  one source code.Depending on the number of source code values,Can we display the values in the report page separated by commas.If the user is selecting 'P','Q','R,'S' as source code values in the prompt page,the report has to display P,Q,R,S in the header.Please assist.Thanks in advance.

Hi,
you can use ParamDisplayValue('parameter') and by default it will be displayed with comma's.
Good luck
