garrContacts = ContactList()

IF garrContacts..Occurrence > 0 THEN
// Sort the contacts
ArraySort(garrContacts, asMember, "+Name")

// Add into the looper
FOR EACH tContact OF garrContacts
LooperAddLine(LOOP_CONTACTS, ...
tContact..Name, tContact..FirstName)
END

STC_NbContacts = StringBuild("%1 contacts", ...
