how to do special date javascript with Chronoforms?

Question

Ok, we did that before on the old Chronoforms for Joomla 1.0.x and never really got it to work, so now that everything on the pages we have is updated to Chronoform 3.0 and Joomla 1.5.9 I would like to try again to figure this out ... so please bear with me.What the scripts (on a non-Joomla, non-Chronoforms page) do is basically the following:a) It changes the 3 select fields of the Arrival Date DAY MONTH YEAR (needs to stay in 3 different fields, as that is what i need to send to the third party form handler) to today's dateb) it changes the 3 select fields of the Departure Date DAY MONTH YEAR (following the arrival date) to TODAY + 1 Dayc) on hitting the submit (book now) button it checks that the arrival date is not before at least today and that the departure date is at least 1 day later than the arrival date ...OK, here is the HTML/JAVASCIPT code for the regular HTML PAGE (outside Joomal and outside Chronoforms):

As you can see the changing of the dates is part of the regular html as script, BUT it calls another Javascript within the form called calendar.js (which I attach to this post as well... but needed to rename it into calendar.txt, as the attachment does not allow .js files...)So, how can I do the same thing in Chronoforms???1)   I created the form (that was the easy part and it works, it sends all the info over to my third party handler ...)2) I tried to copy and paste the Javascript code from the sample above into the FORM JAVASCRIPT box as follows:= ddate ){
                        ddate = new Date( adate.getYear(), adate.getMonth(), adate.getDate()+1 );
                        document.getElementById('DepartureDateYear').value = ddate.getYear();
                        document.getElementById('DepartureDateMonth').value = ddate.getMonth()+1;
                        document.getElementById('DepartureDateDay').value = ddate.getDate();
                }
        }else{
                // if departure date is before arrival date,
                // set arrival date = departure date - 1
                if( ddate  3000 ){ return false; }
