I don't understand if  you are having trouble assigning the form values to 
the array, or accessing the arrays you need from the form splitting them, 
but first you have to manage assingning the form values to the correspondent 
arrays, than you can use them however you like.
Predefined Array length will become unusual if you change the length of the 
form fields in later times.

The following will perhaps be a better way to get the field values of any 
length inside the form:
**************************************************
<html>
<head>

</head>

<body>
	<center>
<form name="farmform">

<input type="text" size="20" value="Cows">
<input type="text" size="4" value="77"><p>
<input type="text" size="20" value="Sheep">
<input type="text" size="4" value="120"><p>
<input type="text" size="20" value="Goats">
<input type="text" size="4" value="3"><p>
<input type="text" size="20" value="Pigs">
<input type="text" size="4" value="3"><p>
<input type="text" size="20" value="Horses">
<input type="text" size="4" value="3"><p>
<input type="text" size="20" value="Mules">
<input type="text" size="4" value="17"><p>
<input type="text" size="20" value="Chickens">
<input type="text" size="4" value="43"><p>
<input type="text" size="20" value="Ducks">
<input type="text" size="4" value="120"><p>
<input type="text" size="20" value="Raptors">
<input type="text" size="4" value="7"><p>

</form>
<Button onClick="farmcount()">GO</button>
	</center>

<SCRIPT LANGUAGE=JavaScript>

	var s=farmform.length;//if you put the 'GO' button inside the Form, write 
s=farmform.length-1
	var fn=new Array();

function farmcount(){

	 for(i=0; i<s; i++) {

		 fn[i]=' '+farmform.elements[i].value;
	}
document.write(document.body.innerHTML +"<b><CENTER>"+fn+".</CENTER></b>");
	}

</SCRIPT>

</body>
</html>

Any further questions...
   -Post at the same forum!
Cheers!
