Hello All,
I am stuck in below trailhead chanllange. Please help me.

Using the Contact standard controller, create a Visualforce page which displays a Contact's First Name, Last Name and the Email address of the Contact's Owner.The page must be named 'ContactView'.
It must reference the Contact standard controller.
It should include a bound variable that uses the standard controller to display the first name of the Contact.
It should include a bound variable that uses the standard controller to display the last name of the Contact.
It should include a bound variable that uses the standard controller to display the Contact Owner's email.

I am getting below error..
Challenge not yet complete... here's what's wrong:
The page does not include a bound first name variable for the Contact record
