calculate days between dates

[rentacar]

Can anyone help a newbie with a form script that will calculate the days between two dates input in a webform by a user? then pass as a field in a form?

Thanks in advance

function dateDiff(){
to = document.form1.date1.value;
from = document.form1.date2.value;
msec = Date.parse(to)-Date.parse(from);//in milliseconds
//convert msec to days
}

where form1 is the name of the form and date1 and date2 are the date fields.
