It is posible to show a row counter on the begin on the rows.
Thenks for Help
Genlock
I found the solution here.
In the code, I found the following:
<?php
$counter = 0;
foreach($records as $data){
$rec_id = ($data['suisa_setlistid'] ? urlencode($data['suisa_setlistid']) : null);
$counter++;
?>
Now, I have inserted the following code in the custom template: <?php echo($counter); ?> and it works."
Thanks
