[thelist] JS breakdown

[7 sinz]

Hi

i have this JS working fine, i dontneed help getting it to work, i laready 
have it working :)

but if i wanted to edit it, i'd need to know the bones behind it.

can someone break this down for me.

function rates() {
	var 
find_rate=document.rate.country[document.rate.country.selectedIndex].value;
	var find_rate2=find_rate.split(",");
	document.rate.Peak.value=find_rate2[0];
	document.rate.OffPeak.value=find_rate2[1];
}

Kind regards

Steven
