It's become variable 'n' dose not exist on the code but only in the function 'diceNum', but i think the first '}' is miss placed in your code.

n can be used only in the function if you wanna use it out of it you have to return it , and something else why you declare a function while you didn't use it?

if you want to avoid "not defined problèms" or use and modify à variable in a function without having to systematicaly have go return it, you can déclaré it outside of your function with a null value for exemple. For exemple : Var n = null; function myfunction(){ n = 10; n++; } myfunction () console.log(n) This code wil print in thé console 11
