Font size

[DungBeetle]

Hi everybody.

I have vb 3.7.3. with with Bluedemon style. ( have a similar postbit_legacy)
What is my problem? I use this code Control User Post Font via Profile Options for vb 3.6.x to make users to chose they default font size color etc...
Im not sure did I make post in right place but I need somebody to tell me is possible to put one code into this bellow code to make default font size,color... if user dont choose in his profile diferent one, because my original default font size is very,very small.

<!-- message -->
		<div id="post_message_$post[postid]">
<!--Custom Font-->
<if condition="$post['fieldXX'] OR $post['fieldXX'] OR $post['fieldXX'] OR $post['fieldXX'] OR $post['fieldXX'] OR $post['fieldXX']">

<span style="font: $post[fieldXX]px $post[fieldXX]; color: $post[fieldXX]; font-weight: $post[fieldXX]; font-style: $post[fieldXX]; text-decoration: $post[field17];">$post[message]</strong></span>

<else />
$post[message]

</if>
<!--/Custom Font-->
</div>
		<!-- / message -->

I try to combine with this Change default post text size/font plugin, but seems that plugin take over everything and user profile font options than is not working
