This is pretty much the code that JimC used(hope you don't mind JimC)I think we all just then stole the code from his post.
<table WIDTH=100><tr><td><br />
<MARQUEE DIRECTION=RIGHT LOOP=INFINITE BEHAVIOR=ALTERNATE SCROLLAMOUNT=30>TextGoesHere</MARQUEE><br />
</td></tr></table>
you can try changing the parameters,especially table WIDTH(how wide the box that the text appears in is)and the SCROLLAMOUNT(text moves faster or slower).
I learnt some html about eight or nine years ago but never saw this until JimC used it so i might mess up.The code contained within the MARQUEE tags is the bit that makes the text move.So the following code,
<MARQUEE DIRECTION=right LOOP=INFINITE BEHAVIOR=ALTERNATE
SCROLLAMOUNT=40>TextGoesHere</MARQUEE>
should do this.
SCROLLAMOUNT=40>TextGoesHere
I cant tell if this is a total disaster until i post it.
