Disaru Graham Yahoo! It work like a charm, Thank you very much

Can I ask one more thing ? thehe
Is there something wrong about this code:

<!--parser:xtscript--> get __filelist_page if $__filelist_page print <meta name="robots" content="noindex, nofollow" />; <!--/parser:xtscript-->

Remeber I said before about xtscript not working only on my homepage? I think the code is the culprit, when I delete it the xtscript on homepage working again?

What I want is to print meta robots no follow, when the url has __filelist_page= query ...
