I have added the following to local.xml file
<?xml version="1.0"?>
<layout version="0.1.0">
<contacts_index_index translate="label">
<label>Contact Us Form</label>
<reference name="head">
<action method="setTitle" translate="title" module="contacts"><title>Contact Us</title></action>
</reference>
</contacts_index_index>
<customer_account_forgotpassword translate="label">
<reference name="head">
<action method="setTitle" translate="title" module="customer"><title>Forgot Your Password</title></action>
</reference>
</customer_account_forgotpassword>
<checkout_onepage_success>
<reference name="head">
<block type="core/template" name="cj_udo" template="app/design/frontend/base/default/template/cj/udo.phtml" />
</reference>
</checkout_onepage_success>
</layout>
location:
/app/design/frontend/base/default/local.xml
However I get this error on my system.log
2014-08-10T11:51:36+00:00 CRIT (2): Not valid template file:frontend/base/default/template/app/design/frontend/base/default/template/cj/udo.phtmlt
