template iframe data merge

In a template I want to merge a data field in an iframe.

<iframe class="embed-responsive-item slideanim" src=" <p>{{Zip_Code_IDX_URL__c}}</p> <p>"></iframe></div></p> <p>How do I format this statement?</p> <p>I get this error: The name can only contain underscores and alphanumeric characters. It must begin with a letter and be unique, and must not include spaces, end with an underscore, or contain two consecutive underscores.</p>

What is your use case here? There may be another way to do this.

The iFrame is rejecting the merge syntax brackets. I’m not sure if you’ll be able to have that functionality in this iframe you’re setting up. Can you provide more information about what you’re attempting here?
