Reply To: Add Select Values from Other Custom Fields

Here is the PHP to show my custom fields:

<?php the_field( 'w' ); ?>
<?php the_field( 'ru' ); ?>
<?php the_field( 't5s' ); ?>
<?php the_field( 't10q' ); ?>
<?php the_field( 't1516' ); ?>
<?php the_field( 't20' ); ?>
<?php the_field( 't3032' ); ?>
<?php the_field( 't40' ); ?>

This is what I want to populate my select options with.
