Reference parameter values in a text box without parameter fields.

You can add the parameter value of a parameter to a text field in you report but after adding you get next content in the text box:

[ERVCountries].[Country].&[Netherlands]

You only want to have: Netherlands

Solution: Change the reference expression to use .Label instead of .Value.
In this example use:

=Parameters!ERVCountriesCountry.Label(0)

To display multiple parameter values you an use next syntax:

="My own text: " + Join(Parameters!Country.Label,", ")
