Syntax error

[Allan]

Hello, I have a problem with this syntax :

{xen:helper snippet, {xen:raw $port.contentHtml}, {$xenOptions.portCharacterLimit}}

This renders :

yfu<br /> <br /> <b>sdf</b>

This displays BBCodes Tags, Where is the error ?
Maybe I need to insert {xen:helper snippet} in the {xen:raw}?

Thanks
