If nothing happens at all, the script might have stopped because encountered an error, and in that case it would be possible to get information about it. Just hit the F12 key after you pressed 'Move' and nothing happened, and an area will open at the bottom of your browser window, with a number of tabs in it. Select the tab 'Console' if that is not already selected. Error messages should appear in there. You can close the area again by another F12.
