@toscho - looking through the plugin documentation: advancedcustomfields.com/docs/getting-started – Matt Jul 3 '12 at 16:25
You didn't look through it all, then. Menu item 4 -> functions -> click "get_field" -> Usage -> if/else example. – SickHippie Jul 3 '12 at 16:34
Matt, Research Efforts = code references you found while looking the documentation + better description of the problem (Do you mean front or back-end?) :.....: Also, the Content of your Question is exactly the same as the Title: it really makes it look like WPSE is a magic box where you drop a one line issue and some solution will self-generate... – brasofilo Jul 3 '12 at 16:38

You can see in the docs that you get the values by get_field(), so do something like this:

$values = get_field( 'field_name' );
if ( $values ) {
    echo 'A value is set';
} else {
    echo 'A value is not set';

Change field_name to your wanted field.
