I may be over complicating this, but I have some event handlers that send plain text emails. I would like to do them as HTML to format them with spaces and make some fields bold, etc.. To get property values, I am using the "Substitute" keyword, so I am not sure how to format this within HTML tags. I have checked the box "Body is in HTML form", but how do I now format the body with HTML tags and still get the values to populate for my properites.
SUBSTITUTE("A New Engineered Order {0} has been created for Customer {1}. The order is dues {2}. Please email a confirmation to {3}.", E(pKey), E(pCustNum), E(pDueDate), E(pEmail))
