Hello again swm023,
This can easily be done from within the Screen your are customizing in the Method Screen Designer. Click on the "Advanced..." button on the top left of the screen, then click "next" until you get to Step 3 of 5 "Tab Ordering". You have the option to move the fields up and down with the arrow keys on the right-hand side, you can also click on the "Order" number which is editable, and change number accordingly.
