Copuld really do with some help with this.

I have been taked with changing someone els's code (never a good thing) and I am stuck

Below is a pice of code that checks if a date is more than 9 months ahead

JavaScript:
	if(checkDD.value.length > 0){
		var d = new Date();
		maxDD = d.setMonth(Today.getMonth() + 9);
		jsMonth = ddmonth.value -1;  //Javascript month values start at 0
		jsDate = new Date(DDyear.value,jsMonth,DDday.value);
		
		if(jsDate > maxDD){
			alert("Please enter a valid due date.");
			return false;
		}
	}

I have created this, which I thought would check if the date is additonally no more than 14 days past

JavaScript:
	if(checkDD.value.length > 0){
		var d = new Date();
		minDD = d.setMonth(d.getDate() - 14);
		jsMonth = ddmonth.value -1;  //Javascript month values start at 0
		jsDate = new Date(DDyear.value,jsMonth,DDday.value);
			
		if(jsDate < minDD){
			alert("Please enter a valid due date, it cannot be more than 14 days ago.");
			return false;
		}
	}

However it doesn't appear to work, the JS file this is in seems to stop at this point and doesn't run a hide command for now required fields, I do not get any error.

I could really do with this clearing this up and i have been stuck on it for a day or so and need to get the website updated.

not tested this but something like this should work

Code:
function validateDate( dateObj ){
	var today = new date();
	var uBound = new date();
	uBound.setMonth(today.getMonth() + 9);
	var lBound = new date();
	lBound.setDate(today.getDate() - 14);
	return (dateObj <= uBound && dateObj >= lBound);
}

/*usage */
if(!validateDate( new Date(DDyear.value,DDMonth.value - 1,DDday.value))){
	//date not ok
}
 
Thanks for the quick response, managede to 'bundle' this through in the end by trial and error, however, going to look at this when i get a second and see if this just works better.
