2nd sentence not writing to the page

I am having trouble concatenating my variables correctly. here's my code below - it works when I run like this:

var answerone = prompt('Give me a Noun');
var sentenceone = 'There once was a man ' + answerone + answertwo;
var answertwo = prompt('Give me a Verb');
var answerthree = prompt('Give me an adjective');
alert('You are done');

sentenceone += ' programmer who wanted to use JavaScript to ' + answertwo;

document.write(sentenceone);

However, it doesn't write when I add the last variable concatenation like below - --- why?

var answerone = prompt('Give me a Noun');
var sentenceone = 'There once was a man ' + answerone + answertwo;
var answertwo = prompt('Give me a Verb');
var answerthree = prompt('Give me an adjective');
alert('You are done');

sentenceone += ' programmer who wanted to use JavaScript to ' + answertwo;

sentenceone += ' at night ' + answerthree;

document.write(sentenceone);

It looks to me that you are making use of answertwo before you create it and assign it a value.

var answerone = prompt('Give me a Noun');
var sentenceone = 'There once was a man ' + answerone + answertwo;
var answertwo = prompt('Give me a Verb');
var answerthree = prompt('Give me an adjective');
alert('You are done');

sentenceone += ' programmer who wanted to use JavaScript to ' + answertwo;

sentenceone += ' at night ' + answerthree;

document.write(sentenceone);

Running the above code results in this:

```There once was a man NOUNundefined programmer who wanted to use JavaScript to VERB at night ADJECTIVE

In order for it to work you would have to arrange the variables like this:

```javascript
var answerone = prompt('Give me a Noun');
var answertwo = prompt('Give me a Verb');
var sentenceone = 'There once was a man ' + answerone + answertwo;
var answerthree = prompt('Give me an adjective');
alert('You are done');

sentenceone += ' programmer who wanted to use JavaScript to ' + answertwo;

sentenceone += ' at night ' + answerthree;

document.write(sentenceone);

However, you'd be as well making things a bit simpler:

var answerone = prompt('Give me a Noun');
var answertwo = prompt('Give me a Verb');
var answerthree = prompt('Give me an adjective');
alert('You are done');


var sentenceone = 'There once was a man ' + answerone + ' '+ answertwo + ' programmer who wanted to use JavaScript to ' + answertwo + ' at night ' + answerthree;

document.write(sentenceone);

I made a Codepen so you can see it in action.

Hope this helps!
