CasperJs Adwords Scraping problem

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. Take a look at the image to see what's the textarea. The code is over here: [login to view URL] I think someone with more experience could fix this right away so it's a quick job. There are more things to be done, so I'm waiting for someone to help me with this stuff.
