Can anyone help me fix my code?

[Jedi6391]

My code used to work but suddenly stopped working and I have no idea why. It is javascript embedded in an html document.

<script language="JavaScript1.1">	

var slideimages = new Array()
  var slidelinks = new Array()
  function slideshowimages() {
  for (i = 0; i < slideshowimages.arguments.length; i++) {
    slideimages[i] = new Image()
      slideimages[i].src = slideshowimages.arguments[i]
    }
}

function slideshowlinks() {
  for (i = 0; i < slideshowlinks.arguments.length; i++)
    slidelinks[i] = slideshowlinks.arguments[i]
  }

function gotoshow() {
  if (!window.winslide || winslide.closed)
    winslide = window.open(slidelinks[whichlink])
    else
    winslide.location = slidelinks[whichlink]
    winslide.focus()
  }

</script>

From body:

<a href="javascript:gotoshow()"><img class="dropshadow"src="images/slideshow_1.gif" name="slide" border=0 width=240 height=180></a>
					
<script>	

//configure the paths of the images, plus corresponding target links
slideshowimages("images/slideshow_1.gif", "images/slideshow_2.gif", "images/slideshow_3.gif", "images/slideshow_4.gif", "images/slideshow_5.gif")

//configure the speed of the slideshow, in miliseconds
var slideshowspeed = 3000

var whichlink = 0
var whichimage = 0
function slideit() {
  if (!document.images);
    return document.images.slide.src = slideimages[whichimage].src whichlink = whichimage
  if (whichimage < slideimages.length - 1);
    whichimage++else
    whichimage = 0 setTimeout("slideit()", slideshowspeed);
  }	
slideit()
					
</script>

Any help would be greatly appreciated.

if (!document.images)[B][COLOR="Red"];[/COLOR][/B]
    return document.images.slide.src = slideimages[whichimage].src whichlink = whichimage
  if (whichimage < slideimages.length - 1)[B][COLOR="Red"];[/COLOR][/B]

The most obvious problem is the semicolons after the if clauses, which should not be there.
