hi all, i am having some issues with coding a form firstly i am new at this and it is seemly frustrating when you don't know what you are doing, here goes; i have 4 drop down menus labeled as with static input as 0-9; JobPerReview1 JobPerReview2 JobPerReview3 JobPerReview4 if for choice the user selects the following; JobPerReview1 = 3 JobPerReview2 = 0 JobPerReview3 = 5 JobPerReview4 = 9 i would like a function/ script to sum the total inputs as an integer or if that's the correct term for it. so it would calculate something like this JobPerReview1 = 3 summed as 1 JobPerReview2 = 0 summed as none JobPerReview3 = 5 summed as 1 JobPerReview4 = 9 summed as 1 i would also like a total box labeled "NOF (number of factors) to calculate the selections such as; NOF = 3 please assist this is starting to be mind bugling function getItems() { var items = new Array(); var itemCount = document.getElementsByClassName("items"); var total = 0; var id= ''; for(var i = 0; i < itemCount.length; i++) { id = "p"+(i+1); total = total + parseInt(document.getElementById(id).value); } document.getElementById('tot').value = total; return total; } getItems();

function getItems()
{
var items = new Array();
var itemCount = document.getElementsByClassName("items");
var total = 0;
var id= '';
for(var i = 0; i < itemCount.length; i++)
{
id = "p"+(i+1);
total = total + parseInt(document.getElementById(id).value);
}
document.getElementById('tot').value = total;
return total;

}
getItems();
