Full Stack JavaScript Techdegree Graduate 18,394 PointsHi I tried attaching the math.js file to the index.html file but when I previewed it, the alert didn't pop up. Help!
At first I thought I didn't write the code correctly, but then I did and still the alert didn't show up. I have no way of testing if any further coding I do will work.

Full Stack JavaScript Techdegree Graduate 18,394 PointsI couldn't do all the numbers below because I couldn't test if any of my code work. Not sure what I'm doing wrong...hope you can help, thanks in advance! :)
// DONE 1. Attach this file -- math.js -- to the index.html file using a <script> tag
// DONE 2. Add an alert to announce the program with a message like "Let's do some math!" alert("Let's do some math!");
// DONE 3. Create a variable and use the prompt() method to collect a number from a visitor var userInput1 = prompt("Type a number.");
// DONE 4. Convert that value from a string to a floating point number userInput1 = parseFloat(userInput1);
// DONE 5. Repeat steps 3 and 4 to create a second variable and collect a second number var userInput2 = prompt("Type another number."); userInput2 = parseFloat(userInput2);
// DONE 6. Create a new variable -- message -- which you'll use to build // a complete message to print to the document // Start by creating a string that includes <h1> tags as well // and the two input numbers. The string should look something like this: // "<h1>Math with the numbers 3 and 4</h1>" where the two numbers are // the values input from the user. Use string concatenation to create this // and make sure you actually perform the math on the values by // using the + symbol to add their values together var message = "<h1>Math with the numbers " + userInput1 + " and " + userInput2 + "</h1>";
// 7. Add another string to the message variable. // The string should look something like this after concatenation: // "3 + 4 = 7"
// 8. Add a linebreak tag -- <br> -- to the message variable
// 9. Continue to add to the message variable to include strings // demonstrating multiplication, division and subtraction // For example: // "3 * 4 = 12" // "3 / 4 = 0.75" // "3 - 4 = -1"
// 10. Use the document.write() method to print the message variable // to the web page. Open the finished.png file in this workspace // to see what the completed output should look like document.write(message);

4,477 PointsOh ok, I didn't look properly.
Ok so since the 'alert' seems to be written correctly, the problem is probably in your HTML. In the workspace, if you look on the left side, you should see that 'math.js' is nested inside the 'js' folder. This means the script tag should look like this:
<script src="js/math.js"></script>
If you already had it written like this, then I would suggest trying the 'console' in Chrome browser. If there is a mistake it should show up, with the line in question.

<script src="math.js"></script> and it worked for me.
