New Post: GetUserProfileByName

I put the responseText in a DIV...
"soap:ServerException of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)."

$().SPServices({
            operation: "GetListItems",
            async: false,
            listName: "User Information List",
            CAMLQuery: "<Query><Where><Eq><FieldRef Name='ID' /><Value Type='Counter'>13</Value></Eq></Where></Query>",
            CAMLViewFields: "<ViewFields><FieldRef Name='LoginName' /></ViewFields>",
            completefunc: function (xData, Status) 
                {
                $("#thisId").html("").append(xData.responseText);
                
                }
            });
