[Plugin: Facebook ,Twitter,Google buttons] Twitter options: additional text to include twitter handl

Hi, I’m trying to get my twitter handle @longlivefit to appear in the text box when people click to tweet a blog post. Under twitter options for this plugin it’s giving me the option to add additional text. It says “optional text added at the end of every tweet, e.g. ‘ (via @authorofblogentry)’.”

However when I add “via @longlivefit #fitnessawayoflife” and click save it’s still not showing up when I click on the tweet icon below my blog posts.

How can I fix this problem?
