This is a take-off on the Live Script I offer in one of my tutorials. This gives the same alert box as the live script, except on this one you don't get to go into the page if you click cancel.
You can personalize the message on the alert box by writing in your own thoughts where the script reads "YOUR MESSAGE GOES HERE." Just be sure to leave in the quote marks.
Please note: This script is being offered in simple text format. When you click to Grab the Script, the text should display. Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
