Hello, 

I created a subscription form display in front end of the website, and I want to received after submiting the form the properties “$language”.
 

<form id="newsletter" 
	action="//manage.kmail-lists.com/subscriptions/subscribe" 
	method="GET" >
	<input type="hidden" name="g" value="XXXXXX">
	<input type="hidden" name="$fields" value="$consent">
	<input type="hidden" name="$list_fields" value="$consent">
	<input type="hidden" name="$language" value="NL">

For now I cannot find in klaviyo BO the language value of the input. I tryed to pass ‘$language’ into the value of $fields but not working.

How can I pass properties througth the form. Do I need to edit $fields or $list_fields values ?
