Problems with { and }

Hi!

I am using the FCKeditor in a simple CMS. A am using a Template Class in php, to parse my templates, wich I can edit with the FCKe.

But the editor kills most of my template variables like {VARNAME} or such things:
<table>
{if data}
{datafromsql}
{else}
<tr>
<td>nodata</td>
</tr>
{endif}
</table>

Is there any way to protect my {TAGS}?
Thanks in forward!
