Creating a Popup window and sending PHP vars to it

Hi, I have the following prob: Ihave a document with articles wich can be saved in the userprofile. When "Save" is clicked, a popup window has to appear containing all saved articles and Buttons to delete them. Therefore I need to get the $userName (Stored in a session) and $aticleID (Stored in a Form) to the popup window. I do not use Cookies for the sess var, but the SID. I can get the UserName to the pop with "link.html?SID", but how do I get the articleID to the window without submitting the form? Can I submit to another Window? Should look like this: Main Doc: _______________________ Article1 Some intersting nes, blabla [save] Article2 Some intersting nes, blabla [save] Article3 Some intersting nes, blabla [save] ________________________ Popup: ________________________ Saved articles: Article 1 [Delete] Article 2 [Delete] ________________________
