How to retrieve data from multiples fckeditors?

Hello,
i have 3 fckeditor in the same form with 3 differents names attributes.

<?php
$oFCKeditor1 = new FCKeditor('spec_technique') ;
$oFCKeditor1->BasePath = './fckeditor/' ;
$oFCKeditor1->Config['EnterMode'] = 'br';
$oFCKeditor1->Value = '' ;
$oFCKeditor1->Create() ;
?>
<?php
$oFCKeditor2 = new FCKeditor('crit_generaux') ;
$oFCKeditor2->BasePath = './fckeditor/' ;
$oFCKeditor2->Config['EnterMode'] = 'br';
$oFCKeditor2->Value = '' ;
$oFCKeditor2->Create() ;
?>
<?php
$oFCKeditor3 = new FCKeditor('description') ;
$oFCKeditor3->BasePath = './fckeditor/' ;
$oFCKeditor3->Config['EnterMode'] = 'br';
$oFCKeditor3->Value = '' ;
$oFCKeditor3->Create() ;
?>

but when i post my data with the submit button, only one of the 3 randomly, have data in it, when the 3 are fulled.

So i wonder how to do this.
