Form fields in an email are not popultaing

Hi all,

I am having a bit of a problem with form fields not populating when I send emails. I have the following code that runs when a form is submitted:

from :zoho.
to :zoho.adminuserid
bcc :EmailAdd
subject :"New Production Added"
message :"<div>A new performance of ${Name_of_Production} has been added to the STAGE application. <a href=\"https://creatorapp.zoho.eu/inedtechsolutions/stage/#Page:Dashboard\" target=\"_blank\" style=\"color: rgb(0, 0, 238);\"> Click here to view</a>. <br></div><div><br></div><div>Kind regards<br></div><div><br></div><div>STAGE Admin Team\"<br></div>"]

When the email is delivered, this is what the recipient gets:

A new performance of ${Name_of_Production} has been added to the STAGE application. Click here to view.

Kind regards

STAGE Admin Team

The name of the field is correct and I have tried different ways of doing this, does anyone know where I am going wrong?
