Passing GUID in querystring

Do I need to use the premium version of the plugin to be able to pass a GUID from a list of records to a detail page?

I was reading previous forum posts and I feel like it’s possible, but when I try it, I just get a blank page back.

My FetchXML is correct — since it runs in FetxhXML Builder just fine — but even hard coding the GUID in the condition returns no results.

This is all of my Twig and HTML:

{% set projectid = request.params['id'] %}
{% fetchxml collection="project" %}
<fetch mapping="logical" returntotalrecordcount="true">
   <entity name="jcma_project">
      <attribute name="jcma_projectid" />
      <attribute name="jcma_name" />
      <attribute name="jcma_difficulty" />
      <attribute name="jcma_projectdescription" />
      <attribute name="jcma_requiredpreferredskills" />
      <attribute name="jcma_city" />
      <attribute name="jcma_stateprovince" />
      <filter type="and">
         <condition attribute="jcma_projectid" operator="eq" value="{{ projectid }}" />         
      </filter>
   </entity> 
</fetch>
{% endfetchxml %}

{% for projectdetail in project.entities.results %}
<div>
   <h1>{{ projectdetail["jcma_name"] }}</h1><br>
   <i>{{ projectdetail["jcma_city"] }}, {{ projectdetail | formatted_value(["jcma_stateprovince"]) }}</i>
</div>
<div>
   <h3>Description</h3><br>
   <p>{{ projectdetail["jcma_projectdescription"] }}</p>
</div>
<div>
   <h3>Required or Preferred Skills</h3><br>
   <p>{{ projectdetail["jcma_requiredpreferredskills"] }}</p>
</div>
{% endfor %}

Any assistance would be appreciated.
