Show/Hide DIV’s Generated Dynamically

Ok, I am very new to JS, but I have had a fair bit of experience in PHP, ASP, .NET (<- bah), pearl and a few others so I know coding concepts ?

Here is my problem: I have an external JS file that I am loading an array from (places[]). I have a form on the page that creates checkboxes from the array as follows:

[CODE] <tr><td>
Place(s) :
</td><td>
<script language=Javascript>
<!–
//<![CDATA[
for(var i=0; i<=places.length-1; i++) {
document.write(“<input type=”checkbox” name=””+places[i]+”” onClick=”HideUnhide(“+places[i]+”Div)”>”+places[i]+”</input>”);
}
//]]>
//–>
</script>
</td></tr>
[/CODE]

The onClick handler that I have put in there is where the problem starts. It is MEANT to display various DIV tags that I have made invlisible like so:

[CODE]
<div id=’BankstownDiv’ style=”display: none;”>
<h2>Bankstown Lecturer</h2>
Same As Unit Coordinator:
<input type=”checkbox” name=”Bankstown” id=”Bankstown” />
Name : <br />
<input type=”text” name=”CLName” /><br />
Location – <br />
Room Number : <br />
<input type=”text” name=”CLRoom” /> <br />
Building :<br />
<input type=”text” name=”CLBuilding” /><br />
</div>
etc…..
[/CODE]

And this is the Javascript function that I have placed in the HEAD of the doco:

[CODE]
function HideUnhide(objectID)
{
if(document.getElementByID(objectID).style.display == ‘none’ ) {
document.getElementById(objectID).style.display = ‘block’;
}
else{
document.getElementById(objectID).style.display = ‘none’;
}
}
[/CODE]

Now when I test it in IE6 I get an error “Object doesn’t support this property or method” and it points me to the following line of code:

[CODE]
function HideUnhide(objectID)
{
[B][U]if(document.getElementByID(objectID).style.display == ‘none’ )[U][B] {
document.getElementById(objectID).style.display = ‘block’;
}
else{
document.getElementById(objectID).style.display = ‘none’;
}
}
[/CODE]

As far as I was aware, the DIV element (which I am referring to, for example, the value for place[2]=”Bankstown” and I simply refer to its DIV tag –which is called BankstownDiv — by stating place[2]+”Div”) DOES have a style.display method…at least that what some JS tutes have indicated, and I can get the DIV’s initially hidden using the style=”display:none;” attribute but I simple can not work out why this script wont run successfully.

Any help would be GREATLY appreciated!! ?

Thanks in advance fellas!
