Why is my one number method working but the two numbers not?

Hi!

My method is a bit different because I tried to make it shorter with less variables. So as the title says, the method for one number is working while the second one for two numbers is not even tho I use the similar method?

One random number:

var topNumber = prompt("Type a number to get a random to it.");

alert(Math.floor( Math.random() * (parseInt(topNumber)))+1);

Two random number:

var topNumber = prompt("Type a top number.");

var bottomNumber = prompt("Type a bottom number.");

alert(Math.floor(Math.random() * (parseInt(topNumber) - parseInt(bottomNumber) +1 )) + bottomNumber);

Thanks in advance.

You didn't use "parseInt" on the last term, so it's being handled as a string instead of a number.
