Weird Forms problem

I have a form page that has two select boxes. When you select from one, it sets the value of the other to ''. However, if you select a value in select1 and then select and value in select2, although the selected option in select1 reverts to a blank it still holds the original seelcted value ( Does that make sense ).

Say select1 has three options: '', 1, 2
If I choose 2 and then choose something from select2 and onChange event kicks in which sets the value of select1 to ''. While on the screen, the focus in Select1 moves away from 2 and back to '', it still holds the value 2. I have used an alert to output the value and this is the case. Can anybody explain this?? Mise Le Meas,

Mighty :)

I'm unable to recreate what you have described... Here's the little example I was playing with -- post yours.

<html>
<head>
<title>Mighty Test</title>
<script language=javascript>
function change(element){
if (element==1){
document.theForm.select1.value='';
alert(document.theForm.select1.value);
}
else{
document.theForm.select2.value='';
alert(document.theForm.select2.value);
}
}
</script>
</head>
<body>
<form name=theForm>
<table width=&quot;100%&quot; border=1>
<tr>
<td><select name=select1 onChange=&quot;change(2);&quot;>
<option value=''>nothing</option>
<option value=1>1</option>
<option value=2>2</option>
</select>
</td><td>
<select name=select2 onChange=&quot;change(1);&quot;>
<option value=''>nothing</option>
<option value=1>1</option>
<option value=2>2</option>
</select>
</td>
</tr>
</table>
</form>
</body>
</html>

lemme know -

link9,

Here's my complete code. The page has a number of select boxes. The user may either select multiple products from the first select or enter a range of products using the second two drop downs. The JavaScript function in the HEAD section then generates a stock level page and outputs it to the screen. If you select a part from the first select and then select a range, although the first select seems to blank it still generates the stock level list based on that selection.
