On your confirm page, you can modify the table to add a new row that will display this. The new table row code should look like this:
<tr>
<td class="eC_SummaryLabel">Service Charge</td>
<td><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->TotalColumn("TotalPrice") * 0.03); ?></td>
</tr>
You can add it right above the total by putting it here:
<?php
//WA eCart Merchandizing Show End
//ecart="eCart1"
}
?>
<tr>
<td class="eC_SummaryLabel">Service Charge</td>
<td><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->TotalColumn("TotalPrice") * 0.03); ?></td>
</tr>
<tr class="eC_SummaryFooter">
<td class="eC_SummaryLabel">Total:</td>
<td><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->GrandTotal()); ?></td>
</tr>
</table>
</div>
<?php
//WA eCart Show If Middle
}
