just noticed the single quotes around the variables throughout here. This will show the text and not show the interpolated variable.

example

current
<pre>
"sshd_use_pam may be either 'yes' or 'no' and is set to '${sshd_use_pam}'."
</pre>

should be
<pre>
"sshd_use_pam may be either 'yes' or 'no' and is set to <${sshd_use_pam}>."
</pre>
