I added a parameter to a report today, which put it the end of the list the user fills in before running the report. I wanted to move it higher up the list but they are presented in a tree structure. You can edit each parameter but there’s no sign of dialogue that lists them (where you might be able to rearrange them). I looked in the help but couldn’t find anything. After a bit of trial and error it turns out you just highlight the parameter and use Ctrl and the up and down arrow keys. Easy when you know how!
