Twenty Ten Child Theme Function Question

I have a slideshow- in Javascript that I want to use.

Here is the code. When I execute it into the functions.php in my Twenty Ten child theme- I get errors. What am I doing wrong?

function slideshow() {
if (is_front_page()) {
?>
  <div class="slideshow">
    <a id="slide1" class="slide" href="https://www.oneotacoop.com"></a>
    <a id="slide2" class="slide" href="https://www.google.com"></a>
    <a id="slide3" class="slide" href="https://www.facebook.com"></a>
  </div>
<div id=slideshowbuttons>
<div style:" height: 40px; width: 40px; float: right;">
<a class="prevbanner" href="#"><img src="https://www.oneotatest.com/wp-content/themes/thesis_182/custom/images/arrowleft.png" /> </a> <a class="nextbanner" href="#"><img src="https://www.oneotatest.com/wp-content/themes/thesis_182/custom/images/arrowright.png" /></a>
</div></div>
<?php

function slide_script() {
echo "\n\n";
?>
