Marquee not getting displayed

I’ve installed this plugin and I’ve given my input as similar to the screenshot given in this forum (http://ww.wp.xz.cn/plugins/marquee/screenshots/). However, I’m not able to see any marquee shown in the home page. Am i missing something here? any help here would be much appriciated.
