1. Change the line that says "set theChoice to "Illinois"" to reflect your state--or if you for some reason want the script to ask you for your state each time, you can change the line to have "--" at the beginning of the line and remove those hyphens from the line that begins "set theChoice to choose from list..."
2. For the lines that say: "set theButton to "Northbrook"" and "set theName to "Northbrook"", change them to reflect your city's name (or, if you want to get asked each time, remove the double hyphens from the two lines above these).
3. For the line that says "set hhh to 5", change the number to reflect the number of hours before sunset you want to be reminded. (You could adapt the script to ask you each time--let me know if you would like help doing this.)
4. You also need to save the copied file in Script Editor or the like (as a script (.scpt) file, not an application) and place it in the "Entourage Script Menu Items" folder under Documents->Microsoft User Data). You can then invoke it from the script menu in Entourage 2004. Or, if you want this script to run every morning, you can get some kind of script automator (so that you don't have to fill up your tasks ahead of time or, on the other hand, to remember to invoke the script each day).
