The Variable Challenge - Syntax Error

Hello,

I am attempting 'The Variable Challenge activity' and seem to be encountering an error with my code that causes my program to stop after prompting for a noun. My goal for the program is to ask the user for a noun, change that input to lower case, and then output that lower cased form on the webpage. I want to repeat this for a verb and an adjective as well.

Any recommendations on what I'm doing wrong and why it is wrong? Thanks!

//Variable list

var noun; var verb; var adjective;

//Prompts for adlibs

noun = prompt("Type in a noun"); console.log(noun); noun = noun.tolowerCase();

verb = prompt("Type in a verb"); console.log(verb); verb = verb.tolowerCase();

adjective = prompt("Type in an adjective"); console.log(adjective); adjective = adjective.tolowerCase();

//Output

document.write("One day, " + noun + "decided to_" + verb + "_" + adjective + "down the street.");

Any recommendations?
