                        <strong>Handling Field Data Types</strong> - most fields you can just pass a string and all is well. For some, though, that is not the case...
                        Field values should be formatted as follows:
                        string address For the string version of an Address, the fields should be delimited by <strong>2</strong> spaces. Address 2 can be skipped. The Country should be a 2 character ISO-3166-1 code and will default to your default country if not set
                        array address For the array version of an Address, the requirements for Address 2 and Country are the same as with the string version. Then simply pass us an array with the keys <strong>addr1</strong>, <strong>addr2</strong>, <strong>city</strong>, <strong>state</strong>, <strong>zip</strong>, <strong>country</strong> and appropriate values for each
    
                        string date use YYYY-MM-DD to be safe. Generally, though, anything strtotime() understands we'll understand - <a href="http://us2.php.net/strtotime" target="_blank">http://us2.php.net/strtotime</a>
                        string dropdown can be a normal string - we <em>will</em> validate that the value is a valid option
                        string image must be a valid, existing url. we <em>will</em> check its existence
                        string multi_choice can be a normal string - we <em>will</em> validate that the value is a valid option
                        double number pass in a valid number - anything else will turn in to zero (0). Note, this will be rounded to 2 decimal places
                        string phone If your account has the US Phone numbers option set, this <em>must</em> be in the form of NPA-NXX-LINE (404-555-1212). If not, we assume an International number and will simply set the field with what ever number is passed in.
                        string website This is a standard string, but we <em>will</em> verify that it looks like a valid URL
