Use Freemarker in Community Structure / Edit Properties

Under Community Structure, I am trying to add the Name and Description of a forum. Rather than typing plain text, i would like to store that string as a value in a data model and print that value as the Name or Description.

I tried putting ${name} and ${desription} into the Name and Description fields, but it prints this as plain text.

The website says "${name}" rather than printing the value of ${name}

Is there a way to get it to print the value?

Thanks!
