Hey I've just created a custom content type for resources, and added the URL field as an option however when I create a new resource and enter the url and the url title I get the following error:

warning: mysql_real_escape_string() expects parameter 1 to be string, array given in W:\www\includes\database.mysql.inc on line 350.

Any idea what that means?

I entered www.domain.com and a url title Domain Name

Thanks
