Padding can be controlled in later versions of filemaker, but I don't think the inspector in 12 had the controls for padding yet. You might want to try removing the style from that object to make it work for now.
you can add a right "margin" to the field and it will push the text to the left.
Look under Inspector when the field is selected.
Right Indents under Appearance I put 20 pts and that seems to do what I wanted. Thanks!
