Storymaker code does not write out my story

I'm recreating the storymaker test on my own. It runs through all of the prompts and alerts fine, but when it comes to accepting the alert, instead of writing out the sentence it leads to "This webpage is not found" what is wrong with my code?

var name = prompt('Give me your Alias');

var type = prompt ("Alright, " + name + " tell me, are you a male, female, or monster?");

var location = prompt ("Do you prefer your adventures in the lab or in the park?");

var activity = prompt ("Would you rather play with fire or eat candy?");

alert("Great! Thanks, I now have all the information I need. Are you ready to check out your adventure!?");

var sentence = "One day, " + name + " was having an adventure";

sentence += "in the " + location;

document.write(sentence);
