[Solved]New Date Field is not working

Hi there,
I've installed a new date field for one of my content types. When I want to submit or edit one of that type, the field is there and gets the value. When I click "apply" it says "Item saved successfully", but the the field is empty as if it's not entered and it doesn't show the field on frontend.
What's problem?

Thanks

What is name of field ?
no space ?
witch browser ?

It's a date type field, named:"تاریخ انتشار مجدد"
Browser" FF 3.6

Thanks

What happened? Anyone? Any suggestion?

Thanks

your field name doesn't have any space ?? (you can insert in label but not in name of field)
does it work on other browser ?

I can insert both in name and label.
It is the same as I mentioned in FF, with IE and Chrome.

Thanks
