Above are possible solutions, but it will always depends on what you're exact requirement is. Try also below:
='Country = ' & Concat(DISTINCT Country,', ')
Concat() function, will provide you list of entity depending on your parameter. For above example, it will give you list of all distinct or unique country names when nothing is selected in list box, and it will show you one country name when selecting one country, so on...
