Hi I’m trying to figure out how old a user is and how many hrs are spent playing video games a day to show how many yrs were spent playing video games. The formula would be years(hoursvideogames*age)divided by 24. I’ve done this before but not with the radio buttons and drop down list. How would I calculate this with the getelementbyID() method. So when they click submit it should write their name and how many years have been spend on the computer. I know I dont have any of the calculations, I didnt want to post them since they’re way off, could someone show me how to get started? I am going to put more age options but didn’t want to post all of them since it makes the code look massive.

<script type=’text/javascript’>
function check(browser)
{
document.getElementById(“answer”).value=browser;
}
<div>
function formValidator(){
// Make quick references to our fields
var firstname = document.getElementById(‘firstname’);
var myAge = document.getElementById(‘age’);
if(isAlphabet(firstname, “Please enter only letters for your name”)){
}
return false;
}
</script>
