Check your JS errors. I get:
Looks like the dates have a "check_in" and "check_out" ID assigned, so since you're using
getElementById, you should probably use those ID's instead of `inFromStr`, etc..
Code:
function clearDates()
{
document.getElementById('Check_In').value = "";
document.getElementById('Check_Out').value = "";
day_bottom="";
day_top="";
}
PS - I personally wouldn't book a hotel/golf package online via an unencrypted form that is posting to an "email" labeled page. (perhaps it will be encrypted down the road..?)
