[Javascript] Help to debug this

[Marcelo Wolfgang]

Hi list,

I need some help, my javascript abilities are very very rusted, and
they never were that good.

Can someone here please tell me why nothing happens in the above code ?

<script type="text/javascript">
	function addToCart(catalogID){		window.location='cart.cfm?act=add&storeOwner=paula&item_id='+catalog.ID+'&prodSize='+getElementByID(prodSizeSelect).value+'&prodColor='+getElementByID(prodColorSelect).value;
	}
</script>

Here's the HTML:

<div id="prodDescription">
	<div id="prodDesc-size">
		<div id="prodSize-dropdown">
			<select id="prodSizeSelect" name="prodSize">
				<option value="P">P</option>
				<option value="M">M</option>
				<option value="G">G</option>
			</select>
		</div>
	</div>
	<div id="prodDesc-color">
		<select id="prodColorSelect" name="prodColor">
		   <option value="dourado">dourado</option>
                   <option value="uva">uva</option>
                  <option value="preto">preto</option>
               </select>
	</div>
	<div id="prodDesc-addToCart"><a href="##"
onClick="document.getElementById('item-added').className='show';addToCart(5);">Colocar
no carrinho<img src="images/prodaddCart_icon.gif" width="16"
height="16" alt="Colocar no carrinho" /></a></div>
</div>

Can anyone tell me what I'm doing wrong here ?

TIA
