A Select External Option field in a repeater field, how to get the value ? [resolved]

[Sten]

Hi,
I can't get the value of the fields of the page whose id comes from the value of the select field. In fact the value I get is the id of the repeater field from an other table with several fields inside.

<?php
//I get the repeater field value
$events= $page->evenement;
//I get the different lines
foreach ($events as $event){
//I get the value of the select field
foreach ($events as $event){
$cat=$event->type;
echo $pages->get($cat)->couleur;exit;

And then my result is empty.

I am now confused with all my trials...

thank you

I securised the variable 

$cat=(string)$event->type;
