English -> French needed

[whatever]

Can anyone help me translating into French:

"Wrong Security Code: The security code you entered did not match the displayed characters. Please try again."

It is for a non-commercial web site where users will have to enter a code (which is displayed) before being allowed to join in (to avoid automatic entries).

kind regards
Whatever

Here is your translation:

Code de sécurité erroné : le code de sécurité saisi ne correspond pas aux caractères affichés. Veuillez réessayer.

Isn't there also "Erreur de saisie de code de sécurité" ?

Correct, Fuokusu! The problem being that you often have a character limit in software strings, in which case a shorter version would be preferable. But in theory, your version is good (I'd just say: "du code de sécurité").
