Cant complete exercise

Hi guys.
I cant seem to complete the last exercise of the back end development course. I have really given it a go but its keeps rejection the solutions. I have no idea what am missing… Any help will be much appreciated.

my solution

app.post(‘/name’, (req, res) => {

var firstName = req.body.first;
var lastName = req.body.last;
res.json({ name: ${firstName} ${lastName} });
console.log(${firstName} ${lastName});

  });

app.get(‘/’, (req, res) => {res.sendFile (__dirname + ‘/views/index.html’);});
