Database Error: Cannot set 'value' as 'undefined' (SourceFile#107)

I am running two queries for my form. The first is a drop down list that is being populated with Vendor Names. The second rule fires off on the selection of the drop down list and populates 3 fields; Phone, Fax, and Email. I have tried everything I can think of to get this to work with the customer's new accounting database, but no matter what I do I can only retrieve the Phone and Fax. It errors on the email every time with the following error:

20:36:04,093  WARN RuleObserver:458 - Error evaluating rule [Purchase Request v2.0.Purchasing Vendor Names Return]: Cannot set 'value' as 'undefined' (SourceFile#107)

Here are my config file entries:

<query name="allVendors">
                <retrieve>
                    <statement> select VendName, ContactEMailAddr, ContactPhone, ContactFax FROM vdvVendorAddr2 order by VendName</statement>
                </retrieve>
            </query>   

        <query name="vendorInfo">
                <retrieve>
                    <statement> select VendName, ContactEMailAddr, ContactPhone, ContactFax FROM vdvVendorAddr2 WHERE VendName ='{reqVendor}'</statement>
                </retrieve>
            </query>

Here is the business rule for the second query:
//Purchasing Vendor Information
    if (reqVendor.value.length >0) {

vendorEmail.value = 'NA';
vendorPhone = 'NA';
vendorFax = 'NA';

  eval ('x=' + http.get('http://localhost:8082/database/mas500vendor/vendorInfo?reqVendor=' + reqVendor.value));
vendorFax.value = x.resultSet[0].ContactFax;
vendorPhone.value = x.resultSet[0].ContactPhone;
vendorEmail.value = x.resultSet[0].contactemailaddr;
}

When I run this query in the address bar, I get a good return.
Here is the query address:
http://localhost:8082/database/mas500vendor/vendorInfo?reqVendor=Top Hat Productions

Here is the return: (of course I modified the return info for this post to not be real information)
