I have a web application that allows a user to upload a file. Before uploading the file, I would like to prompt the user to click "OK" or "Cancel" on a popup confirmation screen. In the confirmation screen, I would like to use some dynamic data stored in a session variable "Site". In summary, the user clicks the button "Upload", then a confirmation box pops up and say "Do you want to upload a file for XYZ Company" < the session variable, user clicks "OK" or "Cancel" and upload routine is executed or canceled. Thaniks for the help.
