Comment 11 for bug 556657

This is the XML that produces both screenshots I submitted. There are several sums in the XML, the two shown in the screenshots are:

                    <field colspan="4" name="line_ids" nolabel="1" widget="one2many_list">
                        <tree string="Receipt Lines" editable="bottom">
                            <field name="reference" string="Invoice Reference"/>
                            <field name="partner_id" string="Partner" select="1"/>
                            <field name="partial"/>
                            <field name="amount" string="Total" sum="Total Invoices Amount"/>
                            <field name="invoice_id" invisible="1"/>
                        </tree>
                     </field>

And:

                            <field colspan="4" name="direct_payment_ids" nolabel="1" widget="one2many_list" on_change="button_compute(context)">
                                <tree string="Direct Payment Lines">
                                    <field name="method_id" select="1" required="1" domain="[('company_id','=', parent.company_id)]"/>
                                    <field name="currency_id" select="1" />
                                    <field name="amount" string="Total" required="1" sum="Total Direct Payment Amount"/>
                                </tree>
                                <form>
                                    <field name="method_id" select="1" required="1" domain="[('company_id','=', parent.company_id)]" />
                                    <field name="amount" string="Total" required="1" sum="Total Direct Payment Amount"/>
                                    <field name="currency_id" select="1" on_change="on_change_currency(currency_id, parent.company_id)"/>
                                </form>
                            </field>
