adding/displaying variables to temlates

I try to customize the teaser and body of one of my content type.

I can add the variables to the template by clicking on the link, but the result is not what I expected.

It shows the value of the variable instead of the object that uses that variable.

For example, I want to show the voting feature and curren voting result (I have nodevote installed), so I clicked on $nodevote->vote_display and $nodevote->vote_do which added the following code to the template:
print $nodevote->vote_display print $nodevote->vote_do

But on the content teaser on the front end, I don't see the nodevote result and feature. I see the BOOLEAN value instead (1 1).

help anyone?
