Hi
You can try something like this with the index when you are doing the foreach loop:
<?php
$repeater = get_field('repeater_name');
$repeaterCount = count($repeater);
foreach ($repeater as $index => $row) {
// if it's not the first row, that means we have a previous row
$previousRow = $index == 0? null : $repeater[$index - 1];
// if it's not the last row, that means we have a next row
$nextRow = $index == ($repeaterCount - 1)? null : $repeater[$index + 1];
... code
}
Cheers
