updating profile, what am I doing wrong?

Hi, I've been trying for about an hour to update my profile and every time I submit, I get a message saying that the date is wrong and does not exist, or something like that, my OH, he's a bit more computer savvy than me, has tried everything, the time and date on my comp is correct.

Any ideas :confused:

 

I believe you need to set your date of birth, MG.

 

Thanks David, all sorted now.
I was trying to keep that bit of information a secret, a lady doesn't like to disclose her age

 

MG, if you leave the box unticked no one will see it.
