No it's not... well... yes it is... but not the right object. It's a string.
Call it like this:

<input type="checkbox" name="sugarcove" onclick="updateValue(this);">

You have to pass reference to the object itself, not just it's name. Now,
change your fuction to this:

function updateValue(propName) {

That should do it. Hope this helps.
