[Zope] dtml-if question

I guess i did something wrong on this, so it's not work? <dtml-if expr="objectValues('newclient')==''"> <br> Null <dtml-else> <br> Not Null </dtml-if> My idea is to test if Zobject-newclient exist in this folder or not. But i always get "Not Null" even tho I'm sure there is no newclient exist in the folder. Can someone help me to fix this? Thanks __________________________________________________ Do You Yahoo!?
