SharePoint UpdateList--Problem--Help

[getobject]

I am building an ASP.Net site and wish to use a SharePoint to hold the information. I am trying to add an entry to a list using Sharepoint webservices and keep getting a SOAP exception. I have know its not a credential problem because I have been successful in using the GetList to bind a list to a gridview. I am running Windows Sharepoint Services 3.0



I created an empty list and wish to use the UpdateList webservice to add an item (row) to a list. I have one column in the list "Title" and wish to grab data from a textbox and update the list.



Here is the code I am using:

Dim doc As New XmlDocument
        Dim updates As XmlElement = doc.CreateElement("Batch")
 
        updates.InnerXml = "<Method ID='1' Cmd='New'><Field
Name='Title'>" + TextBox1.Text + "</Field></Method>"
 
        Dim returnNode As XmlNode =
VideoLists.UpdateListItems("{B3D403D3-73BB-49C7-AD83-9008E085C74C}",
updates)

The error message

Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerExcepti on'
was thrown.
Description: An unhandled exception occurred during the execution of the

I'm afraid, particularly bearing in mind the fully worded and explained question, that this doesn't really fit into the Access Forum very well. I personally, know very little about SharePoint so I wouldn't even know which forum, if any, it would be better suited to.
In the circumstances, I can't think you'll be lucky enough to find a helpful answer. If however, you think another forum here may suit this question better, then please just ask and I will get it moved for you.

Sorry I couldn't be of more help :(
