Hi my following code gives a "Syntax Error" and i have no idea why...

Any basic mistake you can see? 

(* ajouter_itineraire: itineraire -> plan -> plan *)
let  ajouter_itineraire (i: itineraire) (p: plan) = match p with
   | Vide ->[i]
   | Ilist l ->if itineraire_existe(i.num) then
       Err("Itineraire deja present") else i::p.Ilist

Err is an exception taking a string as parameter.

Your code tries to return the exception as a value. I think you want to say raise (Err "Itineraire deja present"). Also p.Ilist looks wrong. Most likely this should be just l.
