The script all works i just dont understand all of it, i have made a few changes but i would like to be able to pull it apart to modify it as i decice to change things.

 

it also has option to use javascript popup wich i dont use

or any of the option not selected below so if someone could run through and just add comment to the scipt with some explination so i can strip it down to what i use that would be awsome

 

 

thanks in advance for any help..
