Registration error, Date format

[marbor]

When i try to registrate a new customer, i get an error code that forces me to change the birthday to the required format. The problem is that the birthday is formated according to the helpline on the right side of the text, and it is not working...

But if i format it according to the default language its working fine.

The default format is:
(eg. 05/21/1970)

The swedish format of is:
(eg. 1970-05-21)

And if i don´t use the default format, i will get an error code.

in your main language file
ie: /includes/language/english.php

look for something like (about line 70):
// text for date of birth example
define('DOB_FORMAT_STRING', 'mm/dd/yyyy');

change to:
// text for date of birth example
define('DOB_FORMAT_STRING', 'yyyy/mm/dd');

or which ever your format is for that language (See lines 20-25 in the SAME file).

Good luck.
