Hello,

I'm trying to complete the Simulate a Cross-Site Scripting Attack but I get the error:

Challenge Not yet complete... here's what's wrong: 
It doesn't appear that you've successfully simulated a cross-site scripting attack using the Visualforce page. Please try again.

My input is: <a onmouseover = "alert(\'This is an xss attack.\')">xss attack</a>
The org is connected to Trailhead, however, it seems that the Trailhead Tracker isn't installed. Isn't this package usually required to track access the orgs used in Trailhead?
