The above is a fully functional script made using copy and paste from the links sent to you by Khatovar, I had to learn nothing, and spent approximately 20mins commenting this for you. Like you I have work and a limited amount of play time, so as you can't be bothered to learn I can not be bothered to help you with the above script. Each section is commented in the hope that your frustration will lead to curiosity, and as such you will be compelled to put in the work to make everything work for you. This will work for 3 clients if you wish to add a couple or get rid of one it will require editting.

If you reach a sticking point, write down what happens and what you expected to happen, and what it is you were doing at the time, this is the only way I will help, simply because this means you have tried to help yourself and don't require a handout.

Good Luck,
Shawn
