Trouble using antispambot()

I think the problem is echo vs return,

i.e. that you are using the_field instead of get_field.

What you’re trying to do is similar to this:

 antispambot( echo( '[email protected]' ) )

but echo returns nothing.

Please try:

<?php $email = antispambot( get_field( 'queries_e-mail' ) ); ?>
