dotnet jscript: I am still a novice in JavaScript, and I am trying to understand what is
going on with these parts. This is some portions of JS on the web form
calculations.
Any feedback is greatly appreciated.

My question is what do the ' f ' & 'o' do here??
---------------------------------------------------------------------------

function calculateForm( o ) {
if(o==null) return;
var f = '';
(typeof(o)=='object') ? f=o.name : f=o;
(f.indexOf('Break')!= -1) ? f='Break' : f='';
.......
var nEstablishedValue =
formatSignedDecimal(getValue('nEstablishedValue'+f));
var nDamage = formatSignedDecimal(getValue('nDamage'+f));
var nWriteDown = formatSignedDecimal(getValue('nWriteDown'+f));

setValue('nEstablishedValue'+f, formatSignedCurrency(nEstablishedValue));
setValue('nDamage'+f, formatSignedCurrency(nDamage).replace('$',''));
setValue('nWriteDown'+f,
formatSignedCurrency(nWriteDown).replace('$',''));
......

}

From what i understand:

The "o" here is pass value or an object pass from the function who called it
and the "f" will be the container of what ever the "o" has..
i may be wrong but its what i understand..
