 .SH DESCRIPTION
 The function \fBset_form_fields\fR changes the field pointer array of
 the given \fIform\fR.  The array must be terminated by a \fBNULL\fR.
-
+.PP
 The function \fBform_fields\fR returns the field array of the given form.
-
+.PP
 The function \fBfield_count\fR returns the count of fields in \fIform\fR.
-

 The function \fBmove_field\fR moves the given field (which must be disconnected)
 to a specified location on the screen.
 .SH RETURN VALUES
-The function \fBform_fields\fR returns \fBNULL\fR on error.
