It is still challenging

I tried and tried, but still tells me Bummer: Cannot read property '1' of null.

app.js 
let firstName = "Shima";
let lastName = "Bahre";
let role = 'developer';
let msg = firstName + ' ' + lastName +':' + role + '.';
let msg = firstName + ' ' + lastName +': ' + role.toUpperCase();

Hi Shima,

Just delete your first "let msg" line. You were only supposed to change it, not write a new one.

Hope this helps!
