    Try placing this inside your function.php file. You have to replace $field_key with your field key. 

    add_filter( 'acf/validate_value/key=field_key_1', function( $is_valid, $value, $field, $input ){
        if( $value == acf_extract_var( $_POST['acf'], 'field_key_2' ) ){
            return $is_valid;
        }else{
            return __( 'The values do not match.' );
        }
}, 5, 4);
