Error message "NaN" with a factorial calculator
I'm trying to create a factorial calculator in Dreamweaver using HTML and Javascript.
I'm encountering an error when I preview the code and try to use the calculator, the error message "NaN" pops up instead of a number. I've been told the error is somwhere in this line of code;
document.getElementById('answer').innerHTML = "Your Answer Is" * a;
but I can't figure out whats wrong with it. I'm quite inexperienced with Javascript and coding so a dumbed down answer would be appreciated.

console.log(a)
