[Typo3] access siteressource in TS

[Carlos Rodriguez]

Hi all,

i have a navigation in TS like this:

constants:
lib.menu {
     linkcap = press me
     linkhref = [link to siteressource here]
}


setup
lib.menu = COA

lib.menu .10 = HTML

lib.menu .10.value (
     <a href="{$lib.menu.linkhref}" class="intern">{$lib.menu.linkcap}</a>
)

This lib is in TV set to a marker. Menu works fine.

But now I want the link href to go to my siteressource, which was 
uploaded to the site in pagetype advanced.

How can I access and out in linkhref?

Thanks
