Hi,
I have the following function which compares the two dates coming from a form. (it fills the day,month,year dropdowns and gets the values from there to compare) I want the script also check if the check-in date (starting) is earlier than today.
I tried to find some scripts on the internet to make it but didn’t work.
I’ll be glad if anyone can help.
Thanks

Here is the JS file (Makes the comparison in calDuration() function.)
function startFunction()

var today=new Date()
dayfield=document.getElementById(“day_start”);
monthfield=document.getElementById(“month_start”);
yearfield=document.getElementById(“year_start”);
var this_month=today.getMonth();
var this_year=today.getFullYear();
var days_in_month=32 – new Date(this_year, this_month, 32).getDate();
for (var i=0; i<days_in_month; i++)
dayfield.options[i]=new Option(i+1, i+1)
dayfield.options[today.getDate()-1]=new Option(today.getDate(), today.getDate(), true, true) //select today’s day
for (var m=0; m<12; m++)
