Move Object - doesn't work

Hi I would like to move an object after clicking on it with my mouse. I searched this forum and tried to use this script

http://answers.unity3d.com/questions/23761/move-selected-object

but it wont work. Do you know why? I have a first person controller with this script put on. In my console the selected object is shown but its not moving.

If you have any idea please post it ;) cheerio andrew
