Smartblock on page

My gliding club’s home page should show a message that tells whether or not flying is canceled today.
URL: http://www.zweef.nl/index.php

Code for this page as shown in the WYSIWYG editor is
[smartblock id=268]
<h2><span style=”color: #ff0000;”>Zweefvliegclub Den Helder
</span></h2>
[two_third_last]
etc ………………

Instructors decide about canceling. Until now, they have to edit such messages with the WYSIWYG editor. Some of them make awful mistakes in doing so. They are excellent glider pilots, but no experienced computer users.
I therefor have written a page that offers all 7 different messages in a prefabricated form under a simple button. An example of code produced:
[do action=”vliegen-briefing-om” datum=”maandag 9 juli” tijd=”12:00 hr”/]
The message: Op maandag 9 juli wordt gevlogen. Briefing om 12:00 hr. (Monday July 9 we fly. Briefing at 12:00.)

In the home page’s source code I see:
/form>
</div>
</div></div><!– .sidebar –>
<div class=”content right”>
<div class=”box box3 left”><b>Op maandag 9 juli wordt gevlogen. Briefing om 12:00 hr.</b></div>
<h2><span style=”color: #ff0000;”>Zweefvliegclub Den Helder
</span></h2>

My problem: how to upload this smartbox directly without using the WYSIWYG editor?
I’m new to WordPress, but a rather experienced VB6 programmer.

Thanks for your help, Gerard Hageman
