Conditional Statements Quiz Challenge

I made up my own questions for this quiz however I could not get the code to run. I then went back and copied the code shown in the video. I saved and previewed but prompt boxes are not showing to move through the quiz. I am not sure what I am doing wrong. I did try the console but it didn't show the error. Thanks for your time in advance.

var correct = 0;

// ask questions var answer1 = prompt("Name a programming language that's also a gem"); if (answer1.toUpperCase() === 'RUBY') { correct += 1; } var answer2 = prompt("Name a programming language that's also a snake"); if (answer2.toUpperCase === 'PYTHON') { correct += 1; } var answer3 = prompt("What language do you use to style web pages?'); if (answer3.toUpperCase === 'CSS') { correct += 1; } var answer4 = prompt("What language do you use to build the structure of the web pages?"); if (answer4.toUpperCase === 'HTML') { correct += 1; } var answer5 = prompt("What language do you use to add interactivity to a web page?"); if (answer5.toUpperCase === 'JAVASCRIPT') { correct += 1; }

// output results document.write(<p>You got " + correct + " out of 5 questions correct.<p>");

// output results if ( correct === 5 ) { document.write("<p><strong>You earned a gold crown!</strong></p>"); } else if ( correct >= 3 ) { document.write("<p><strong>You earned a silver crown!</strong></p>"); } else if ( correct >= 1 ) { document.write("<p><strong>You earned a bronze crown.</strong></p>"); } else { document.write("<p><strong>No crown for you!</strong></p>); }

The console shows you have 3 errors:

(1) Prompt begins with double quotes but ends in single quote

var answer3 = prompt("What language do you use to style web pages?');

(2) What you are passing to document.write needs to be enclodes in quotes 

// output results
document.write(<p>You got " + correct + " out of 5 questions correct.</p>");

should be 

.write("<p>

note: I fixed the closing </p> tag as well.

(3) Same here with document.write. There is a beginning quote but no end quote.

document.write("<p><strong>No crown for you!</strong></p>);

In addition to this toUpperCase() is missing the parentheses in 4 of the 5 questions. This will lead to the incorrect count of correct answers being displayed.

Thank you. I should have looked a little harder.

Hi Jason, You many problems in your code...

  1. document.write(<p>You got " + correct + " out of 5 questions correct.<p>"); There is only a closing double quote. You forgot the first one in the beginning.
  2. document.write("<p><strong>No crown for you!</strong></p>); same as 1, only this time it is the closing quotaston mark that is missing.
  3. answer.toUpperCase() - only the first if statement is correct. You forgot '()' at the rest of the statements.
  4. var answer3 = prompt("What language do you use to style web pages?'); As you can see the string quotation starts with a double quotation mark and ends with a single one.
