javascript link not working in firefox

[cscwebmaster]

Hi I have a numbered image gallery which has a next and previous link which is another way of navigating through the gallery the problem i have that in IE all is fine but doesnt seem to be working in firefox, i would appreciate afew pointers,
regards.

here is the code

<script type="text/javascript">
var currentImage = 1;

function LoadGallery(picNum, captionText)
{
var footer = document.getElementById("footer");
// get the array of all <a> elements in the footer:
var links = footer.getElementsByTagName("a");
// and unclick (change color back to normal) of the current link:
links[currentImage].style.color = "#ffffff";

// then change which is current image
currentImage = picNum; // save current picture number
// and change color of new current link:
links[currentImage].style.color = "#ff9900";

// rest the same
var picture = document.getElementById("childhood_drawings");
if (picture.filters)
{
picture.style.filter="blendTrans(duration=1)";
picture.filters.blendTrans.Apply();
}
picture.src = "../images/childhood_drawings/" + picNum + ".jpg";
if (picture.filters)
{
picture.filters.blendTrans.Play();
}
document.getElementById("topbar").innerHTML = captionText;

return false; // cancel the click
}

function moveBy(what)
{
// where is user asking us to move to??
var moveTo = currentImage + what;
if ( moveTo < 1 || moveTo > 20 ) return; // can't move too far left or right

var footer = document.getElementById("footer");
// get the array of all <a> elements in the footer:
var links = footer.getElementsByTagName("a");
// and then click on that link:
links[moveTo].click( );

return false; // cancel the click
}
</script>

and these are the links that dont work

<a href="#" onclick="return false moveBy(-1)">&lt;</a>
<a href="#" onclick="return false moveBy(+1)">&lt;</a

and these are the links that dont work

<a href="#" onclick="return false moveBy(-1)">&lt;</a>
<a href="#" onclick="return false moveBy(+1)">&lt;</a

Incorrect syntax. The function returns false, so use: <a href="#" onclick="return moveBy(-1)">&lt;</a>
