When running test with spreadsheet google doc getting error as "API key required" for webpagetest.org

When running test with spreadsheet google doc having WPT public instance getting error as “API key required” for webpagetest.org

And if I run the same test with spreadsheet google doc having WPT private instance then getting following error
“DNS error: http://localhost:4000//runtest.php?url=https%3A%2F%2Fwww.abbott.com%2F&k=&f=json&location=ec2-eu-west-1%3AChrome&runs=3&video=1&fvonly=1

Can any one please provide its resolution?
