Displaying Chosen Parameters in SSRS Report

Hi,

I am finalising an SSRS report and in the header I am displaying the selected parameters to assist the user. One particular Parameter has 35 possible options to choose from.

Could anyone advise me the best way to achieve the following: -

1) if less than 6 Selections made in the Parameter, list the parameter labels

1) If More than 6 selections are made, show "Multiple" instead of listing all of the choices made

2) If all 35 Parameter options are selected, simply show "All" Rather than list all 35 options!

I know you can join the parameters using =Join but I would like to know if the above is achievable. I've been playing around with IIF statements but cant seem to get it right.

Thanks

Glenn
