Pass Guid as String in XmlHTTP

I can't figure out where I'm going wrong...I am new at this and trying to get the whole concept. Any assistance would be GREATLY appreciated!

Using the code below, I am able to get this alert:

Alert oXmlHTTP.responseXML.xml:

< xml version="1.0" >

<string xmlns="http://tempuri.org/">A1 Client TEST</string>

oXmlHTTP.responseXML.xml.toString().length: 84

Then the alert:

Inside check to see if we have a valid response

Then the alert:

Service Returns parentaccount back in a string node: A1 Client TEST

(this is the name of the parent object I am trying to return - I also need the GUID returned as a string, which is where I'm lost; I know the object type code = 1 for Account)

Last alert:

999Inside Exception

I am able to run the parentaccount code - this brings up a website with a link for RetrieveAccount

I enter in the TEST Values of my Project object:

Id: 6415DF41-F023-DB11-BC70-001422B41910
Entity Type Code: 10000
<INVOKE> returns

< xml version="1.0" encoding="utf-8" >
<string xmlns="http://tempuri.org/">A1 Client TEST</string>

A1 Client TEST is the Account Name that I am trying to populate on the form. I also need to get is the GUID as a string.

Here is the entire code

Listing 1 onLoad.js

Alert oXmlHTTP.responseXML.xml:

< xml version="1.0" >

<string xmlns="http://tempuri.org/">A1 Client TEST</string>

oXmlHTTP.responseXML.xml.toString().length: 84
