New Post: Creating a new list item using UpdateListItems

Can someone provide information on how to use the UpdateListItems service to create new list items in list "B" from the information entered into list "A"? I am attempting to create a new associate list item based on the details entered into a project list item. The project list item will have details such as title, project ID, assigned resources, etc. I need to create a new associate list item in list "B" for each assigned resource indicated, while reusing the project record data.

List A Example: (Title / ProjectID / Assigned Resources)

Project SP / 1234 / David, Sally, Walter

individual List B Examples:

Project SP / 1234 / David
Project SP / 1234 / Sally
Project SP / 1234 / Walter

Heres a snippet of the code Im using which essentially creates a new list item at PreSave until all assigned resources have been used.

var revisedResources = updatedARvalue.split(";");
var rLength = revisedResources.length

 var singleAR="",i=rLength;

while (i != 0)
{
var singleAR = revisedResources.shift();

$j().SPServices({
    operation: "UpdateListItems",
    batchCmd: "New",
    listName: "{CAC80717-DB02-4140-BF50-0F1EA65CD70A}",      

valuepairs: [["ID",i],["Title",prTitle],["ProjectID",prID],["Assigned_x0020_Resource",singleAR]],

        debug: false,
        completefunc: null 
});

--i;
}

I dont know why this is not working properly; any help is appreciated.
