<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>
<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>
<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.
