 Hi, im trying use the WebService method UpdateListItems. But  it  doesn't work.

I have some custom fields in my LIST, and this fields i cant insert, just the nom custom fields...

A exemple of my code:

           IDMethod++;

            businessXml.AppendFormat("<Method ID='{0}' Cmd='New'>", IDMetod);
            businessXml.Append("<Field Name='ID'>New</Field>");
            businessXml.Append("<Field Name='people_x0020_name0'>11111</Field>");
            businessXml.Append("<Field Name='habilit' Type='Text'>1</Field>");
            businessXml.Append("<Field Name='Title'>asfdsadf</Field>");
            businessXml.Append("<Field Name='Life_x0020_Of_x0020_Cicle'>asdfasdf</Field>");
            businessXml.Append("<Field Name='Begin'>2005-05-05</Field>");
            businessXml.Append("<Field Name='End'>2005-05-05</Field>");
            businessXml.Append("</Method>");

from the GetListItems webService i get that fields, for example:

 ows_Title

ows_people_x0020_name0

ows_Begin

some body can help-me?

please 

My Problem always was that I used wrong fieldnames.

Sharepoint has the unfair nature not to show the internally used fieldnames. (f.e. if you rename a custom field you only change the caption of the field not its database-name).
What you see is not! what is used by Sharepoint.

I use a CAML Viewer to find the orginal names (you can get a good tool here: http://www.codeplex.com/SPCamlViewer).

 Another good source of information is here: http://blogs.msdn.com/infopath/archive/2007/03/26/submitting-to-a-sharepoint-list.aspx

 Hope this helps to get things working.
