Hi, Jarod,
There are several ways to interpret what you meant by "size of the form
field text", but I don't think Suzi picked the right one.
If you're referring to the font size, first select the field (while
protection is off) and press Shift+F9 to toggle the field code. Between the
keyword FORMTEXT and the closing field brace, type in the switch
\* MERGEFORMAT
Make sure there's a space after the T. Press Shift+F9 again to toggle off
the field code. Then select the field and set the size as you would for any
other text. [Note: this rigamarole is necessary because without it, when you
change the font size and reprotect the document, the field will return to
the same size as the surrounding text.]
If you meant the width of the field when the user first sees it, then open
the Properties box and type a bunch of hard spaces (Ctrl+Shift+spacebar) in
the Default Text box. In an ordinary text form field there are 5 spaces, as
you can see if you toggle on nonprinting characters.
