I dont have a clue about javascript i normally use php
I have a problem i cannot solve using php.


Basically i have a number of listboxes with quantitys in them and i want to get the total of the quantitys for all the listboxes on the current page and have it displayed at the top of the page.These listboxes can be changed by the user on the page and when this happens i want to check the value again.

Any help would be much appreciated

var frm = document.forms[0];
var val1 = frm.select1.value;
var val2 = frm.select2.value;
var total = Number(val1) + Number(val2);
alert(total);

Glenn why forms[0]?

I don't know the form name that bunny1 uses so I just use forms[0] to refer to the first form. Of course, this can be changed to whatever the form name is.
