Hi am writing a module that will inherit from sale.order basically is a sales / quotation system for our service department. I keep getting an error in my xml and can't see where i'm going wrong any help would be great. I have read the documentation and

<record model="ir.ui.view" id="repair_form_view">
    <field name="name">repair.form</field>
    <field name="model">repair.repair</field>
    <field name="inherit_id" ref="sale.view_order_form"/>
    <field name="arch" type="xml">
        <form string="Repair Order" version="7.0">
            <header>
                <button name="repair_confirm" states="draft" string="Confirm Repair" class="oe_highlight"/>
                <button name="send_quotation" states="draft" string="Issue Quotation" class="oe_highlight"/>
                <field name="state" widget="statusbar" statusbar_visible="draft,confirmed,done"/>
            </header>
            <sheet string="Repair Order">
            <h1>
                Repair Order <field name="repair_ref" class="oe_inline"/>           
            </h1>
            <group>
                <group>
                    <field name="partner_id"/>  
                    <field name="state"/>           
                </group>
                <group>
                    <field name="receivedDate"/>
                    <field name="make"/>
                    <field name="model"/>
                    <field name="serialNo"/>            
                </group>
            </group>
            <notebook>
                <xpath expr="//field[@name='order_line']/tree" position="attributes">
                <attribute name="editable"/>
            </xpath>

            </notebook>



        </sheet>
            <div class="oe_chatter">
                <field name="message_follower_ids" widget="mail_followers"/>
                <field name="message_ids" widget="mail_thread"/>
            </div>
        </form>
    </field>
</record>

I cant even seem to get this to work....

<record model="ir.ui.view" id="repair_form_view">
    <field name="name">repair.form</field>
    <field name="model">repair.repair</field>
    <field name="inherit_id" ref="sale.view_order_form" />
    <field name="arch" type="xml">
    <data>
    <field name="client_order_ref" position="after">
    <field name="make" />
    <field name="model" />
    </field>
    </data>
    </field>
</record>
