问题
My parameter field allows multiple values. How can I show all of these values at the top of the report? Currently it only shows one value at a time.
回答1:
If your parameter is dynamic and takes the form of an array, you'll need to join the values together via a Formula:
Join ({?Parameter},", ")

Activate the Can Grow property for that field. Put this field in a new section so it can easily grow based on your content.
