Coding the size and location of a new window opened via a link

I want to be able to control the size of the window that is opened when someone clicks on the link inside this code. I want it to be 400px x 400px. But I also want to know how to change that if I decide to change the size of the new box in the future. Also, I want to be able to move the position of the box. I want it 2 ways. 1. The entire contents of the main box would appear at the bottom right of any size screen folks may be viewing on. 2. The entire contents of the box would appear at the bottom of any size screen folks may be viewing on. But, I would like to possibly move the box left or right. I assume that would be by virtyue of some sort of px positioning. I would need to know how to change that left to right position. I understand that may mean that I would have 2 sets of code. One for the 400x400, bottom right. One for the 400x400, bottom and 'floating' left to right. You can see a sample of the box at the following link. It should appear about 5 seconds after you land on the page: <[login to view URL]> I can supply the code upon approval of bid. ## Deliverables I want to slightly modify this project. I We want to be able to change the href destination. However a normal href url change does not work. Here is where we want the redirect to go: <!-- Begin Volusion Live Chat --> <div align="center" id="VolusionLiveChat"><a href="[Free'>[login to view URL]">Free][1] Live Chat Software</a></div> <script defer type="text/javascript" src="[[login to view URL]"></script][2]> <!-- End Volusion Live Chat --> Plus, I have attached the original code that needs to be changed for the window size and location. * * *This broadcast message was sent to all bidders on Friday Mar 4, 2011 3:34:43 PM: We have just updated the project and atached the code that would need to be altered. Please review the information and revise your bids accordingly. We look forward to your final fixed number. Thanks
