Errors in database

[auntie22]

Hello,

I am not sure if this is the correct area for max 1.5 but hopefully someone can help me.

I got this error while entering a birthdate incorrectly: Warning: checkdate() expects parameter 1 to be long, string given in /home/sizzli2/public_html/catalog/create_account.php on line 80

Can someone help me with this.

Also I have done some test shopping and for some reason items like the printer, a killer switch will be added to the order after check out, I try to remove these items in the edit mode but it does not add the items correctly after that so I must cancel the order all together.

I am also have an issue when entering product attributes, if I enter a color it comes adds it twice same line number but it also shows up twice in the select drop down box.

and last my best sellers is not showing on my right column.

Any help would be apreciated.

Thank you.
