If/Else Template

Hello,

For my carousel, I need to output carousel-item active for the first image, and then carousel-item for the remaining images. I thought I could use Perch's if/else. Here's my code:

<perch:before>
<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
            <ol class="carousel-indicators">
                <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
                <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
                <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
            </ol>
            <div class="carousel-inner" role="listbox">
</perch:before>

<perch:if id="1">
                <div class="carousel-item active" style="background-image: url('<perch:content id="carousel_image" type="image" w="1900" h="1080" label="Carousel image">')">
                    <div class="carousel-caption d-none d-md-block">
                        <h3><perch:content id="carousel_title" type="text" label="Carousel title" required></h3>
                        <perch:content id="carousel_body" type="textarea" label="Carousel body" markdown editor="markitup">
                    </div>
                </div>

 <perch:else>
                    <div class="carousel-item" style="background-image: url('<perch:content id="carousel_image" type="image" w="1900" h="1080" label="Carousel image">')">
                    <div class="carousel-caption d-none d-md-block">
                        <h3><perch:content id="carousel_title" type="text" label="Carousel title" required></h3>
                        <perch:content id="carousel_body" type="textarea" label="Carousel body" markdown editor="markitup">
                    </div>
                </div>
</perch:if>

<perch:after>
            </div>
            <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
          <span class="carousel-control-prev-icon" aria-hidden="true"></span>
          <span class="sr-only">Previous</span>
        </a>
            <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
          <span class="carousel-control-next-icon" aria-hidden="true"></span>
          <span class="sr-only">Next</span>
        </a>
        </div>
    </perch:after>

The content item's ID is actually 3 (for the first image) and I tried that as well. The code is outputting carousel-item active for all content items.

Thank you for your help.
