Passing cck values to webform

Hi all,
I've a webform with three textfield with a %get[somevalue] inside, and a node made with cck.

I want to make a cck field with a default text as a link "click here" that pass by url the three values.
One is the node title, the others are values stored in two cck texfields.

How can I realize this?

I've tried with

<a href="/webform_page?somevalue=$title">CLICK HERE</a> in some variations, else setting the input format to php and putting the php tags before and after

I've tried also something like

  $nome = $title; (and with $node->title too)
  echo "<a href=\"webform_page?nome=$nome\">Click Here</a>";

but I can't get the node title or also.

I'm very basic with php, so i'm sure i've missed something....
