Values after the loop

Hello, I need help in the following code.
It’s strange because ‘$postIDSkateA[0]’, [1] & [2] are full, I am sure than containg values.

<?php

if ( !empty( $postIDSkate ) ) {
foreach ( $postIDSkate as $id ) {
$postIDSkateA[] = $id;
}
}

$coordenadasSkate1 = get_post_meta($postIDSkateA[0], ‘coordenadas_skatepark1’, true);
$coordSkate1 = explode (‘,’, $coordenadasSkate1);

$coordenadasSkate2 = get_post_meta($postIDSkateA[1], ‘coordenadas_skatepark2’, true);
$coordSkate2 = explode (‘,’, $coordenadasSkate2);

$coordenadasSkate3 = get_post_meta($postIDSkateA[2], ‘coordenadas_skatepark3’, true);
$coordSkate3 = explode (‘,’, $coordenadasSkate3);

?>

The explode is for separate the value in two.

It’s very strange because I can print $coordSkate2, but no $coordSkate1 and $coordSkate3

What is it happen?

Thanks for the help. Im really locked..
