Can anyone help me understand why this won't work?

I'm not sure if it's the code or the math I'm struggling with. If I change the inputs from prompts to just inputting the number it seems to stay within parameters. I've looked at several questions, working codes and want to try figure it out for myself rather than just watching the solution...

I've added the parseInt() which I forgot to add to change the string into a number, and added the missing semi-colon. Is this code right now? I'm riddled with self-doubt on this challenge!

See the final example on this page for the formula

Math.floor(Math.random() * (max - min + 1) ) + min;

Note: the final min is not included in the floor function
