reason for a "Notice:.." on one site but not another? (Same code.)

[John Butler <govinda.webdnatalk@xxxxxxxxx>]

Hi sunday  coders,

I've been using this kind of logic on one PHP site I work on to  
display one thing or another depending on whether the form was  
submitted or not:

		if($_POST['UserWishesDateRange']) {  //--line 79
			echo'submitted';
		} else {
			echo'NOT submitted';
		}

and it works great on that site.

But on another site it still works, but gives this error:
Notice: Undefined index: UserWishesDateRange in /home/vs/site/phvs/bl/ 
7solarsecrets/admin/trackingcode.html on line 79

I assume that is because the error display settings are set to a more  
rigorous level in this latter site.
Is this correct?

(Both sites reside on servers where I am not the admin.)
