Hi Barry
Thanks for getting in touch. Address book doesn't have check boxes next to items in the card when viewed normally. However, when you click the Edit button in Safari autofill prefs it opens up Address book at the card and it does then have check boxes. It seems reasonable to hink that these are something o do with he information you want autofilled, right?
I already thought about the first entry and rejigged the info such as the required number was at the top - no joy.
In frustration, I've deleted the card and created a new one with only the info I want entered and that seems to have worked.
Thanks all.
