I don't have Mac, but let me guess. You have a <DOCTYPE> tag at the top of your script and the rest of the coding doesn't follow the XHTML standards. This could cause it to not show up to well in some browsers. I didn't get much time to look through the rest of it, but I always use xhtml. I always close tags. <input type="text" /> or <br /> I also use code to hide my javascript.

<script>
<!--

// -->
</script>

These are just some ideas though.
