Field & Add More Button Positioning

Hi,

I'm working on a form that allows the user to add an additional 9 lines to their request. I've created the form, created 10 fieldsets (line1, line2 etc) and checked the "Add More" attribute on each. Each fieldset contains 4 fields (m1, s1, p1, d1 in line1, m2, s2, p2, d2 in line2 etc).

The form basically works, but I need more flexibility in laying out the form. Specifically:

1 - the 4 fields in the fieldset need to be oriented horizontally. The fieldset is oriented vertically and I don't see a way to update the layout of the fieldset.

2 - After dropping the 10 fieldsets on the page, the "Add More" button shows at the bottom of the 10th fieldset, 9 of which are not yet visible, so the button is well below the user's focus. I'd like to have this button show by default under the last "active" fieldset, so when the first button is pushed the button drops under the line2 fieldset when it's displayed, and when pushed again moves under the line3 fieldset.

Your help would be greatly appreciated.
