Javascript Calculator no longer works in FF. Other browsers OK.
I have a javascript calculator that has suddenly stopped working in FF. I have upgraded from 3.5.8 to 3.6.3 but no changes. IE, Safari, Chrome and Opera all work fine.
Calculator can be found at http://www.hydrastop.be/hprodCalc.html

var one = eval(document.theForm.elements[0].value) var two = eval(document.theForm.elements[1].value) var m2 = Math.round(one * two) squareMeters.innerHTML = m2 Error: squareMeters is not defined
It seems the code doesn't declare squareMeters beforehand.
Hi
Afraid that didn't help. BTW when I posted this question I could not see what I was typing at all. All fields looked blank but cursor moved along. drop downs were empty. But I see the post worked :-)
Thanks for trying. The script was working for about 4 months, then it stopped. Basically in FF you click the submit 'Resultaat' button and nothing happens.

Having a badly written script that used to work for whatever reasons of lax implementations is no excuse not to improve the script when implementations follow the standards more closely.
I fixed the script (locally) by declaring everything and there is no change in Firefox. That is what I meant to say. I will improve the script but it doesn't solve the issue.
I see that the answer that I posted yesterday got lost by restoring a forum backup, so I'll repost my answer. I see that you have already applied the change that I had suggested. --- You need to use document.getElementById. See https://developer.mozilla.org/en/DOM/document.getElementById
function doMath() {
var one = eval(document.theForm.elements[0].value);
var two = eval(document.theForm.elements[1].value);
var m2 = Math.round(one * two);
var m3 = Math.round(one * two);
var maxhstopqty = Math.round(m2 / 5);
var minhstopqty = Math.round(m2 / 8);
var minhblockqty = Math.round(m2 / 5);
var maxhblockqty = Math.round(m2 / 3);
document.getElementById('squareMeters').innerHTML = m2;
document.getElementById('squareMeters2').innerHTML = m3;
document.getElementById('minhstopReq').innerHTML = minhstopqty;
document.getElementById('maxhstopReq').innerHTML = maxhstopqty;
document.getElementById('minhblockReq').innerHTML = minhblockqty;
document.getElementById('maxhblockReq').innerHTML = maxhblockqty;
}
