How to select multiple options from specific repeater row?

I am trying to display multiple select values on the frontend.

This code currently works when the multi-select option is turned off, and correctly display images for one field that is selected without issue. However, nothing works for multi fields when I turn the option on (no matter how many are selected).

Can anyone spot what’s missing?

functions.php:

function acf_load_college($field)
{
	$field['choices'] = array();

	if (have_rows('gallery_repeater', 'option')) {
		while (have_rows('gallery_repeater', 'option')) {
			the_row();

			$value = get_row_index();
			$label = get_sub_field('college');
			$field['choices'][$value] = $label;
		}
	}
	return $field;
}
add_filter('acf/load_field/name=choices', 'acf_load_college');
add_filter('acf/settings/row_index_offset', '__return_zero');

Displaying on frontend:

<?php
		$field = get_field_object('choices');
		$value = $field['value'];

		$rows = get_field('gallery_repeater', 'option');
		$specific_row = $rows[$value]; //dumping this returns null when multi-select option is turned on, but returns correct repeater array for selected value when multi-select is off

		$sub_field_value = $specific_row['gallery'];
		?>

	<?php foreach ($sub_field_value as $img) : ?>
	   <div data-src="<?php echo esc_url($img['sizes']['large']); ?>" title="<?php echo esc_attr($img['title']); ?>">
		<img src="<?php echo esc_url($img['sizes']['large']); ?>" alt="<?php echo esc_attr($img['alt']); ?>" title="<?php echo esc_attr($img['title']); ?>" />
		</div>
        <?php endforeach ?>
	</div>
</div>

For anyone interested, or has had the same issue, I solved this myself. Value to become values and the singular value to loop through each array item:

<?php
		$field = get_field_object('choices');
                $values = $field['value'];

                foreach ($values as value) :

		$rows = get_field('gallery_repeater', 'option');
		$specific_row = $rows[$value]; 

		$sub_field_value = $specific_row['gallery'];
		?>

	<?php foreach ($sub_field_value as $img) : ?>
	   <div data-src="<?php echo esc_url($img['sizes']['large']); ?>" title="<?php echo esc_attr($img['title']); ?>">
		<img />" alt="<?php echo esc_attr($img['alt']); ?>" title="<?php echo esc_attr($img['title']); ?>" />
		</div>
        <?php endforeach ?> // $img
	</div>
<?php endforeach ?> // $value
