NR > 1 ---> to Skip the first line ( header line )

NF ---> Last field ( in your case its 6 )
$(NF-1) --> 5th field value ( 14000 )

form_field_opts(3X)form_field_opts(3X)NAME
form_field_opts - set and get field options
SYNOPSIS
#include <form.h>
int set_field_opts(FIELD *field, Field_Options opts);
int field_opts_on(FIELD *field, Field_Options opts);
int field_opts_off(FIELD *field, Field_Options opts);
Field_Options field_opts(const FIELD *field);
DESCRIPTION
The function set_field_opts sets all the given field's option bits (field option bits may be logically-OR'ed together).
The function field_opts_on turns on the given option bits, and leaves others alone.
The function field_opts_off turns off the given option bits, and leaves others alone.
The function field_opts returns the field's current option bits.
The following options are defined (all are on by default):
O_VISIBLE
The field is displayed. If this option is off, display of the field is suppressed.
O_ACTIVE
The field is visited during processing. If this option is off, the field will not be reachable by navigation keys. Please notice that
an invisible field appears to be inactive also.
O_PUBLIC
The field contents are displayed as data is entered.
O_EDIT
The field can be edited.
O_WRAP
Words that do not fit on a line are wrapped to the next line. Words are blank-separated.
O_BLANK
The field is cleared whenever a character is entered at the first position.
O_AUTOSKIP
Skip to the next field when this one fills.
O_NULLOK
Allow a blank field.
O_STATIC
Field buffers are fixed to field's original size. Turn this option off to create a dynamic field.
O_PASSOK
Validate field only if modified by user.
RETURN VALUE
Except for field_opts, each routine returns one of the following:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_CURRENT
The field is the current field.
E_SYSTEM_ERROR
System error occurred (see errno).
