Troubleshooting Data Entry (Windows SharePoint Services 2.0)

I get a message that I didn't type a valid date

Dates must be in the correct format such as MM/DD/YYYY or M/D/YY. Note that the actual date format may vary depending upon the locale specified for the site on the Regional Settings page in Site Administration.

If the Web address includes a space, type %20 for the space. For example, https://example.com/my%20site

All mailto: addresses must be in lowercase letters. For example:

someone@example.com

I can't edit an item with a date column

You can't edit a list item that has a date older than 1900 or greater than 8900. To resolve this problem, delete the item and add it with a date between the year 1900 and 8900.
