format / input mask

[feardiz]

I'm using Access XP
I'm seting up a date field, the data type is date already
I'd like formating and the input mask to use dd-mm-yyyy it doesn't see
to be a problem to use / but I want -
I'm using the short date format with 99\-99\-0000;;_ mask
either are working, when I try to enter a date the - are there but it
complaining about some other data entered here
Also short date uses / and not - how do I change the formating?

thanks
Joh
