Moving the order of prints

[baybillyt]

I am trying to move files around to put them in a certain order within lightroom. All I get is the circle with a cross hatch across it that will not let me move. At other times I can go to a different shoot and move the files at will. Any ideas what's causing this?

I went to sort and it will not let me click on user order.

If moving within a folder, it must not have subfolders. Otherwise, you can sort in Collections (dumb ones).
