Contact Window using Ajax

I have a contacts link on my site that opens a new browser window with a landlord's contact information. You can click it here? <[login to view URL]> There is also a contact link at the below site that does a similar task, but it does not open a new browser window and appears to use Ajax or a similar technology.? <[login to view URL]> I would like my contacts window to open like their contacts form opens. The mod would need to be written using PHP (along with javascript, CSS, etc). Forgive me if my use of the term Ajax is not correct, but I think you can get the idea. Thanks, ## Deliverables A couple things to note: 1.) Upon request, I cna provide the page(s) that you will need to modify so you can stitch in your code, send me the page, and then I'll try it on my server with my site and verify the mod works. 2.) When opening the additional form/window by clicking the Contacts Link, I will need to pass a php variable (contactID) through the link and? into the form to retrieve the landlord's information and dispaly it in the new form/window.
