Hi Trying to print the payment details after issuing the check/payment.

I am using the following code:

 <?xml version="1.0"?>
<t t-name="account_check_writing.report_check">
 <t t-call="report.external_layout">
    <t t-call="report.html_container">
        <t t-foreach="docs" t-as="o">
            <div class="page">
      <div class="row">
        <div class="col-xs-5 col-xs-offset-7">
          <address t-field="o.partner_id" t-field-options="{&quot;widget&quot;: &quot;contact&quot;, &quot;fields&quot;: [&quot;address&quot;, &quot;name&quot;], &quot;no_marker&quot;: true}"/>
        </div>
      </div>
         <h2>
          <strong>Payment Voucher:</strong>
                <span t-field="o.number"/>
       </h2>
      <div class="row mt32 mb32">
        <div class="col-xs-2">
          <strong>Payment Date:</strong>
                <p t-esc="formatLang(o.date , date=True)"/>
        </div>
      <div class="col-xs-3">
          <strong>Payment Amount:</strong>
                <p  t-field="o.amount" t-field-options="{&quot;widget&quot;: &quot;monetary&quot;, &quot;display_currency&quot;: &quot;o.currency_id&quot;}"/>
        </div>
      </div>
                <table class="table table-condensed">
                    <thead>
                        <tr>
                            <th class="text-left">Due Date</th>
                            <th class="text-right">Reference</th>
                            <th class="text-right">Original Amount</th>
                            <th class="text-right">Open Balance</th>
                            <th class="text-right">Payment</th>
                        </tr>
                    </thead>
                    <tbody>
                      <tr t-foreach="get_lines(o.line_dr_ids)" t-as="l">
                        <t t-if="formatLang(l['amount']) != '0.00'">
                            <td>
                                <p t-if="l['date_due']">
                                    <span t-esc="formatLang(l['date_due'], date=True)"/>
                                </p>
                            </td>
                            <td class="text-right"><span t-esc="l['name']"/></td>
                            <td class="text-right"><span t-esc="formatLang(l['amount_original'])"/></td>
                            <td class="text-right"><span t-esc="formatLang(l['amount_unreconciled'])"/></td>
                            <td class="text-right"><span t-esc="formatLang(l['amount'])"/></td>
                        </t>
                       </tr>
                    </tbody>
                </table>
            </div>
        </t>
    </t>
</t>
</t>

My problem is with the following line:

---

                            <td class="text-right"><span t-esc="l['name']"/></td> 

there is no reference number (supplier invoice / system reference) being printed. What is the variable that should be used to print that?
