adding custom select boxes in the donation form

[developtogetherpk]

I have added 3 custom select boxes in the donation form using this code snippet:

add_action('givewp_donation_form_schema', function ($form) {
// Ensure the GiveWP FieldsAPI is loaded
if (!class_exists('Give\Framework\FieldsAPI\Select')) {
error_log('GiveWP Select class not found!');
return;
}

// Ensure the form object is of the correct type
if (!($form instanceof \Give\Framework\FieldsAPI\DonationForm)) {
    error_log('Invalid form object provided!');
    return;
}

// State Select Box
$stateField = \Give\Framework\FieldsAPI\Select::make('state')
    ->label(__('State', 'give'))
    ->placeholder(__('Select a state', 'give'))
    ->defaultValue('');


    // Zip Code Select Box
$cityField = \Give\Framework\FieldsAPI\Select::make('city')
    ->label(__('City', 'give'))
    ->placeholder(__('Select a city', 'give'))
    ->defaultValue('');


// Zip Code Select Box
$zipcodeField = \Give\Framework\FieldsAPI\Select::make('zipcode')
    ->label(__('Zip Code', 'give'))
    ->placeholder(__('Select a zipcode', 'give'))
    ->defaultValue('');


// School Select Box
$schoolField = \Give\Framework\FieldsAPI\Select::make('school')
    ->label(__('School', 'give'))
    ->placeholder(__('Select a school', 'give'))
    ->defaultValue('');

// Insert the fields after the email field
try {
    $form->insertAfter('email', $stateField);
    $form->insertAfter('state', $cityField);
	$form->insertAfter('city', $zipcodeField);
    $form->insertAfter('zipcode', $schoolField);
} catch (Exception $e) {
    error_log('Error inserting fields: ' . $e->getMessage());
}

});

this added select boxes under the email input. now I want to move the select boxes under the donation levels, for this purpose I tried this code snippet:

add_action('give_fields_after_donation_levels', function ($collection) {
// Ensure the GiveWP FieldsAPI is loaded
if (!class_exists('Give\Framework\FieldsAPI\Select')) {
error_log('GiveWP Select class not found!');
return;
}

// State Select Box
$stateField = \Give\Framework\FieldsAPI\Select::make('state')
    ->label(__('State', 'give'))
    ->placeholder(__('Select a state', 'give'))
    ->defaultValue('');

// City Select Box
$cityField = \Give\Framework\FieldsAPI\Select::make('city')
    ->label(__('City', 'give'))
    ->placeholder(__('Select a city', 'give'))
    ->defaultValue('');

// Zip Code Select Box
$zipcodeField = \Give\Framework\FieldsAPI\Select::make('zipcode')
    ->label(__('Zip Code', 'give'))
    ->placeholder(__('Select a zipcode', 'give'))
    ->defaultValue('');

// School Select Box
$schoolField = \Give\Framework\FieldsAPI\Select::make('school')
    ->label(__('School', 'give'))
    ->placeholder(__('Select a school', 'give'))
    ->defaultValue('');

// Append the fields to the collection
try {
    $collection->append($stateField);
    $collection->append($cityField);
    $collection->append($zipcodeField);
    $collection->append($schoolField);
} catch (Exception $e) {
    error_log('Error appending fields: ' . $e->getMessage());
}

});

but this code is not working and I don't know what I am missing. can anyone help me to resolve this problem
