Access Perch Form ID's?

I am using Zurb Foundation's Range Finder within a Perch Form

Is there a way to access the 'form1_" perch prepends to the input ID's?

I have tried

<perch:content id="perch_item_index" type="hidden" />

but that is obviously incorrect.

My template Markup looks like this:

 <perch:form id="contact" method="post" app="perch_forms">
  <div class="row">
    <div class="small-3 columns">
       <label id="sliderLabel">Daily Rate</label>
     </div>
    <div class="small-6 columns">
<!-- Need to feed in the perch form ID below -->
      <div class="range-slider round" data-slider data-options="display_selector: #<perch:content id="perch_form_index" type="hidden" />_day-rate; step: 50; initial:100; start: 100; end: 2000">
       <span class="range-slider-handle" role="slider" tabindex="0" aria-labelledby="sliderLabel"></span>
       <span class="range-slider-active-segment"></span>
     </div>
    </div>
    <div class="small-3 columns">
       <perch:input type="number" id="day-rate" value="100"  />
       <perch:error for="day-rate" type="required">Please select an amount</perch:error>
    </div>
<...>
 </perch:form>

I need to do this as I am using the template twice on the same page.

Thanks!
