/*****************************************************************************************************************
Div overlay v1
Code developed by TNS Global Interactive dept
Developer: Dominic Claxton
TNS October 2007


Div overlay JavaScript for dynamic overlaying of informational adds or prompts

Current setup allows for: 
delayed popup, 
minimum pages visited before popup, 
leaving site popup.

Currenlty tested to work in: 
IE 5,6,7
FireFox 2
Netscape 7,8
Safari 3 on the PC (apart from the close browser popup)
******************************************************************************************************************/


//PARAMETERS - TO EDIT

//x and y position where div will appear on the page
D_Div_xpos = 30;
D_Div_ypos = 100;

//Life of the cookie in days
D_cookieLife = 14;

//Sets the number range for the randomnum which only shows an overlay for x number of people
// It is worth noting that this random number generator is only mimicing a random number
//So the numbers below equal a 1 in 2 chance of the overlay being shown to the respondent
D_NumberRange = 1;
D_triggerNum = 1;


/*
These two parameter below work control the timed delay div popup and the x number of pages visited popup.
If one is turned off then the other should be turned on - and viceversa
*/
//This turns on/off the time delay on=yes  off=no
D_turnOnTimeDelay = "yes";
//Turns on/off the page visited function. Will show the overlay when x number of pages have been visited on=yes off=no
D_turnOnPageVisit = "no";


//The delay time in seconds when the overlay will show
D_delayTime = 4;

//The number of pages you must visit in order to trigger the overlay
D_pages2visit = 1;

//Enter the domains where this popupcode will be served, preceded by a |
D_domainCheckers = "|visitlanecounty.org";


//The cookie name
D_check_name = "181579cookie";

//This turns on/off the onclose/on exit script on=yes off=no
//It is currently not recommended to use this function because of the different results it returns in different browsers. 
//However, please seek advise from Global interactive if interested
D_turnOnCloseBrowser = "no";
