Remove Order Number From Invoice Email

My client wants the order number removed from the invoice email. Any way of going about doing that?



cheers,



Glen

Mail >orders > edit invoice.tpl



{hook name=“orders:invoice_order_status_info”}



[color=#ff0000] [/color]



Have just changed in 2.2.3:

{if $doc_id_text}{$doc_id_text}
{/if}



Now is only showing invoice number on generated PDF.
