It just doesn't work!

Hello all.

I am new at this javascript thing. I have been working on a room area calculator that calculates room size in both square feet and square yards.

Problem is ... it doesn't work. And I don't know why.

This is what I have got:

<script LANGUAGE="JavaScript">
function roomArea() {
length = parseInt(document.areaform.length.value);
width = parseInt(document.areaform.width.value);
lengthwidth = (length*width);
document.areaform.area.value = area;
}
function roomArea2() {
length = parseInt(document.areaform.length.value);
width = parseInt(document.areaform.width.value);
lengthwidth = (length*width)/9;
document.areaform.area2.value = area2;
}
//
</script>

Length:
 
Width:
 
Square Feet:
Square Yards:

X

Any help would really be appreciated.

Thanks
