The process to attach a file from your computer to an assignment requires that a current version of Sun Java (a free program), be installed on your computer. A Java applet runs when you click the My Computer icon in the Choose Files window when adding an attachment to your assignment. This applet allows you to select and attach multiple files. Please check the Computer Requirements section and download the correct version of Sun Java.
Also, it is important that you do not use any special characters in the filename of the assignment file you are attempting to attach. The best rule of thumb for naming any file that is to be displayed or handled on the web, is to use only letters, numbers, dashes, or underscores. Do not use characters such as ( )~!@#$%^&*,”:’?></| in the name of your file.
