My code works, but it's a lot shorter and different than the suggested solution. Did I do something wrong? 

var userInput = prompt("Give me a number between 1 and 100.");
var userInput2 = prompt("Give me a smaller number.");
var userMax = parseInt(userInput);
var userMin = parseInt(userInput2);
document.write(Math.floor(Math.random()*(userMax - userMin) + userMin));

yeah, i think the +1 is important, if the difference between the two numbers is only 1. floor will will always be 0. Math.random is explained as "Return a random number between 0 (inclusive) and 1 (exclusive)". If it were inclusive, your code would be okay, i think.
