Got 2 functions :   gengo_get_cat_intro & gengo_id_from_mk.
gengo_cat_intro calls gengo_id_cat.
An ID should be returned.
The problem is that :
-gengo_cat_intro "launches" gengo_id_from_mk.  It works because it echoes 477.
But the line after; I return this ID to use it back in gengo_get_cat_intro; and there, it tells me $intro_id does not exists !!!
Did I miss something ?

THanks !

	$gengo_current_id = implode(',', $gengo->language_preference_id);
