How to show captcha error message using the Silverstripe honeypot module? - silverstripe

Question

I am trying to implement the honeypot spam module here:
https://github.com/studiobonito/silverstripe-spamprotection-honeypot
It is showing up fine in the source code because it is a hidden field using this:
$Fields.dataFieldByName(Captcha).Field
However when there is a value added to the field it throws a validation error (which is correct). My problem is I can't get the message to appear on the front end. I am trying to use:
<span class="form-error">$Fields.dataFieldByName(Captcha).Message</span>
But no luck..
If I render the form like this
$ConactForm
The error messages shows when there is a value added. How do I show the error message using my way though?
