This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to set up some custom validation for a post Form. I would like to require at least one term from a custom taxonomy.
Solution: Use the cred_form_validate API to test the value of the taxonomy field, and return an error if none is selected.
function tssupp_require_sector($field_data, $form_data) {
// Split $field_data into separate $fields and $errors
list( $fields,$errors ) = $field_data;
// validate specific form
if ( $form_data['id']==2454) {
// check at least one of required taxonomies set
if ( empty( $fields['p-carer-time']['value'] ) ) {
$errors['p-carer-time'] = 'You must choose at least one sector';
}
}
return array($fields,$errors);
}
add_filter( 'cred_form_validate', 'tssupp_require_sector', 10, 2 );

Hi, are during-the-day, during-the-evening, and over-night different taxonomies, or different terms in the same taxonomy? Based on the names, I am guessing these are 3 terms in the same taxonomy. If I am guessing correctly, your code should be updated like this:
function tssupp_require_sector($field_data, $form_data) {
// Split $field_data into separate $fields and $errors
list( $fields,$errors ) = $field_data;
// validate specific form
if ( $form_data['id']==2368) {
// check at least one of required taxonomies set
if ( empty( $fields['schedule']['value'] ) ) {
$errors['schedule'] = 'You must choose at least one sector';
}
}
return array($fields,$errors);
}
add_filter( 'cred_form_validate', 'tssupp_require_sector', 10, 2 );
Replace schedule with the slug of the taxonomy that contains the 3 terms. If I have misunderstood, let me know and I'll take a closer look.
