Did the syntax coding change since the video has been produced? I copied the code exactly as the "here's my solution". ?

I have a blank screen, no prompts... Then I notice others changing the format to using $ and {} so here's what I have...

var firstName = prompt("What is your first name?");
var lastName = prompt("What is your last name?");
var completeName = FirstName.toUpperCase()+ ' ' + lastName.toUpperCase();
var characterCount = completeName.length;
alert('The String $ {completeName} is $ {characterCount} characters long.');

Hi there, Gypsy Miles! There are a couple of things going on here. First, the variable FirstName is not defined which is why nothing is showing.

You currently have this:

var completeName = FirstName.toUpperCase()+ ' ' + lastName.toUpperCase();

But you meant:

var completeName = firstName.toUpperCase()+ ' ' + lastName.toUpperCase();

Finally, your template literal contains single quotes instead of backticks. The backticks are incredibly important and there should not be spaces between the dollar signs and the curly braces.

So where you have this:

alert('The String $ {completeName} is $ {characterCount} characters long.');

That should be:

alert(`The String ${completeName} is ${characterCount} characters long.`);

Hope this helps! :sparkles:

Thank you! I didn't know what backticks were, just found it on the keyboard. This practice is also requested before learning what String are and how to do, no the less I am learning so much... Once completed with the Strings lesson, I'll come back to redo the practice. Cheers!
