[Zope] Newbie question on passing arguments

[Rengasamy, Samy]

I have a DTML Method:
	<dtml-let webUrl="getRelativePath(rel=absolute_url(relative=1),
ip=hostIP)">

calling a script:
	def getRelativePath(rel, ip):
	    weburl = ip + rel 
	    return weburl

And getting the following error:
	Zope ErrorZope has encountered an error while publishing this
resource.
	Error Type: Type Error
	Error Value: getRelativePath() takes no arguments (2 given)

What am I missing here...?

Thanks,

Samy Rengasamy.
