function output as form value

You need to access the text box and set its value, e.g.

Code:

document.getElementById("text_box_id").value = total;

I think i was too unclear:P I meant to have the final amount to be entered into the textbox after the visitor presses the button. I'll try to simplify the code a bit(coz the total code is 161 lines...)

Code:

<html>
<head>
<script>
function add(){
var q1=document.myForm.productname.value;
t1=q1*15.30;
total=t1
alert("€ "+total);}
</script>
</head>
<body>
<form name="myForm">
<input type="text" name="productname">
<input type="text"name="total">
<input type="button" onclick="add()" value="total">
</form>
</body>
</html>

so what i want to do is have the total to be written in the last text box named total(maybe your code was right but i put it in the wrong spot, i just put it as last line of the add function now)

thanks
