HTML box to open in new window?

[TheBulldog]

Need some help...I have an html feature that gives the weather from weather.com on my site. However, if someone enters their zip code and hits enter, it takes them directly out of my site and into theirs. (can be seen at otterskin.com)

Is there a way to change properties (tried right clicking on the html box and all it brings up is html code) or edit the actual html code to bring up a new browser, or tab in their current browser, so they do not "leave" my site?

Thanks!
Scott
