Showing Reporting Services Multi-Value Parameters

I had a question about showing Multi-Value Parameters in your report. You can’t just show Parameters!Country.Value bacause a Multi-Value Parameters isn’t a string but an Array.
 
To show a Array as a single string you can use the function Join, so like this:
Join(Parameters!Country.Value,”,”)
Now you put all the selected parameter values seperated by a comma on your report.
