not used frontpage before, but here's wot i would do normally...
extract that script so that the files r all in the same place on your computer, then create a html document in frontpage and insert this into it
<center>
<APPLET
CODE = "Applet1.class"
NAME = "TestApplet"
WIDTH = 300
HEIGHT = 80
ALIGN = Middle>
<param name=PLANETS value=10>
<PARAM name=RED value=255>
<PARAM name=GREEN value=70>
<PARAM name=blue value=70>
<PARAM name=PERIOD value=150>
<PARAM name=amplitude value=25>
<PARAM name=fadelen value=32>
<PARAM name=message value="Nemesis was here">
</APPLET>
</center>
(that was taken from the scroll.html in the file without the advertising shite)
anyway basicly to change what you want it to say, just replace the text where i've put "Nemesis was here" with wot u want, but make sure to keep the " " so like "test"
hope that helps, if not let me know!
