BLock users code, HELP!!!! Options

[misskitty_purrs]

Ok, i used the block user code found here...Block User Code and i put it on my site last night so that i could block a certain person. Well today, a friend asked me to put it on her site too. So i did, and all i did was change the name of the blocked person, and now it's not letting her get into her own account. HELP???? But it works fine on mine. Now no one can see her site. Her site
Ok is it because when i put the code in, i didn't take out the extra "USERNAME" spot? this is what i put in the webstats box.
