CasperJs problem filling a textarea

So I just started coding in casperjs and I am struggling for a few hours how to bypass something. Maybe someone more capable than me could help me fix my problem.
I'm trying to crawl something from adwords and I'm stuck completing a form for keywords.

You can pm me or contact me via skype if…
