<terminated> Upon script run

Stupid question, I know. But, what am I missing here?

I am just getting back into Ruby after a few years away.

This code (*See attached JPEG) is just a snippet I’m hacking away at to
ensure watir is installed correctly and can be called.

Upon run, I am receiving the error: .

I am not sure why.

Any advice or push in the right direction would be greatly appreciated.

Thank you in advance,
Matty

require 'rubygems'
require 'watir'
require 'selenium-webdriver'

#start the browser up
def chrome
Watir::Browser.default = "chrome"

browser = watir::Browser.start  "http://www.weather.com/"

browser.text_field(:id, "whatwhereForm2").set("san diego, ca")

browser.button(:src,"http://i.imwx.com/web/common/searchbutton.gif").click

browser.link(:text, "10-Day").click

end

You’ve defined the method “chrome”, but you haven’t called it. The
script terminates because it has completed all its actions: requiring
and defining.

Thank you, Sir. I shall try this now.
