Problem JavaScript in Ubuntu

[VictorJota]

Hi everybody,

I'm a new user here. I have a problem with Javascript using Scribus in Ubuntu linux. I can not add script to action. I've made this http://wiki.scribus.net/canvas/How_to_simulate_Radio_Buttons_on_PDF_forms, but I can not write in the window to put the code. I have probed with Windows version, and It's possible.
I use Ubuntu 12.04.3 x64 LTS, and I've installed Java.
Have to do some previous configuration?
Help please

Thank you

I don't know what the problem might be but Java has nothing at all do to with javascript. They just share a similar name.
