Automatically filling web forms using Watir (Ruby)

I need to automatically filling 2 web forms using Watir (Ruby) using 'watir-webdriver' on Chrome for Windows (I'm using WinXP and Win7). This forms include a WYSIWYG editor and upload files. I can let you know the website and the credential if you need to test it first. The source code I need is like this: require 'watir-webdriver' browser = Watir::[login to view URL] :chrome [login to view URL] "[login to view URL]" [login to view URL](:text, "Login").click browser.text_field(:id, "username").wait_until_present browser.text_field(:id, "username").set("myusername") browser.text_field(:id, "password").wait_until_present browser.text_field(:id, "password").set("mypassword") [login to view URL](:value,"Login Now").click Watir::[login to view URL] { [login to view URL] "SUCCESSFULLY LOGIN" } [login to view URL] "http://mywebsite/[login to view URL]"
