I am having an issue with size.
Here is my code:

<!-- message -->
  <div id="post_message_$post[postid]">
<!--Custom Font-->
<if condition="$post['field17'] OR $post['field18'] OR $post['field19'] OR $post['field20'] OR $post['field21'] OR $post['field22']">
<span style="font: $post[field17]px $post[field19]; color: $post[field18]; font-weight: $post[field20]; font-style: $post[field21]; text-decoration: $post[field22];">$post[message]</strong></span>
<else />
$post[message]
</if>
<!--/Custom Font-->

Can you please tell me what I have done wrong and why it won't work? I am on 3.7.0

Thanks!
