<div class="checkout-content" data-step-id="payment">

    <ul class="checkout-options payment">
        {foreach $checkout_payment_methods as $m}
            <li class="row {if !empty($m.error)}gray{/if}{if $m.id == $payment_id} checked{/if}">

              	<div class="col-md-4 col-sm-4">
	                <h3>
	                    <label class="styling">
	                        <input {if !empty($m.error)}disabled="disabled"{/if} type="radio" name="payment_id" value="{$m.id}" {if $m.id == $payment_id}checked{/if}>
	                        <span class="label-text">
	                        	{if !empty($m.logo)}<img src="{$m.logo}" class="method-logo shadowed">{/if}
	                        	{$m.name|escape}
	                        </span>

	                    </label>

	                </h3>
                </div>



                <div class="col-md-8 col-sm-8">
	                {if $m.description}<p>{$m.description}</p>{/if}
	                {if !empty($m.error)}<p class="error"><em>{$m.error}</em></p>{/if}
	                {if !empty($m.custom_html)}<div class="wa-form" {if $m.id != $payment_id}style="display:none"{/if}>{$m.custom_html}</div>{/if}
                </div>



            </li>
        {foreachelse}
            <li>
                <em class="error">[`Oops! We are sorry, but <strong>we can not offer any payment option for your order</strong>. Checkout can not be completed.`]</em>
            </li>
        {/foreach}
    </ul>
    <script>
        $(".checkout-options.payment input:radio").change(function () {
            if ($(this).is(':checked')) {
                $(".checkout-options.payment .wa-form").hide();
                $(this).closest('li').find('.wa-form').show();

                $('.checkout-options li').removeClass('checked');
                $(this).parents('li.row').addClass('checked');
            }
        });
    </script>

    <!-- plugin hook: 'frontend_checkout' -->
    {* @event frontend_checkout.%plugin_id% *}
    {foreach $frontend_checkout as $_}
    <div class="block">{$_}</div>
    {/foreach}

    {if !empty($error)}
    <div class="checkout-result error">{$error}</div>
    {/if}
</div>

В файле всё верно.
