Hi, Everyone.. I am having a trouble. Challenge Not yet complete... here's what's wrong:
Could not find a button name 'Google_Info' on a Contact page layout.
My task is Add a custom button to a contact
Ursa Major Solar wants to be able to look at their contacts’ internet footprints. Create a custom button so users can do this right from a contact record.
Create a custom button for the Contact object
Label: Google Info
The custom button opens a link to http://google.com?q={!Contact.Name} (where {!Contact.Name} is the current contact's name)
Add the custom button to the Contact Layout page layout

I am doing all the steps which i knew and found from trailhead community but im getting the same error.

1. I have made it a custom button and not link.
2. The API also says Google_Info.
3. I added it to custom button in contact layout..but still im getting the error message. 
Im adding screenshots for reference. Anyone has any idea what is wrong here?
