@daniel-santos I don’t see any reason why your validation would not work, the only thing I can think of is that you’re comparing strings when you want to be comparing numbers, you could try making sure that you’re comparing numbers

add_filter('acf/validate_value/name=initial_pos_val', 'my_validate_function', 10, 4);

function my_validate_function($valid, $value, $field, $input) {
    $valMin = intval($_POST['acf']['field_5abca98844f1c']);
    $valInicial = intval($_POST['acf']['field_5abcb00ba1ff6']);

    if ($valInicial < $valMin ) {
        $valid = "Error: The value is not allowed.";
    }
    return $valid;
}
