　　<option>This select option list will

　　<option>scroll text by copying

　　<option>the top line to the bottom

　　<option>line before deleting the

　　<option>top line. This moves the

　　<option>options up one line and

　　<option>gives the impression of

　　<option>scrolling.

　　<option>You can leave as many

　　<option>blank lines as you feel

　　<option>necessary to give the

　　<option>look of begining and

　　<option>ending.

　　<option>This script was written

　　<option>in response to those

　　<option>who wanted a news

　　<option>scroller to work within

　　<option>a table's cell and for

　　<option>those who want old

　　<option>browsers to also see

　　<option>a scoller on the page.
