trying to select a dropdown in internetexplorer

[kate2000]

Hello,
I am trying to select a dropdown from the webpage. Here is the source-code

<div role="presentation" id="x-auto-272" class="x-combo-list x-ignore x-component x-border " style="border-width: 1px; z-index: 1003; visibility: visible; height: 95px; width: 
 
498px; left: 330px; top: 288px;"><div tabindex="0" hidefocus="True" id="x-auto-224" class=" x-view x-combo-list-inner x-component  x-unselectable" unselectable="on" 
 
 
style="overflow-x: hidden; padding: 0px; border-width: 0px; height: 95px; width: 498px;"><div role="listitem" class="x-combo-list-item  x-view-highlightrow x-combo- 
 
 
selected">Electrolux</div><div role="listitem" class="x-combo-list-item ">Walmart</div><div role="listitem" class="x-combo-list-item">Petsmart</div><div role="listitem" 
 
 
class="x-combo-list-item">Toyota</div><div role="listitem" class="x-combo-list-item">Nokia</div></div></div>

I have tried all these ---

ie.Document.all.Item("x-auto-224").selectedindex = 2, Doc.getElementById("x-auto-224").selectedindex = 2. 
 
IE.Document.getElementById("x-auto-272").Focus 
IE.Document.getElementById("x-auto-272").selectedIndex = 2 
IE.Document.getElementById("x-auto-272").FireEvent ("onchange") 
 
Set methodFld = ieDoc.getElementById("x-auto-224") 
 
methodFld.Value = "WALMART"

But nothing worked. I am trying to select Walmart out of the list.

Thanks in advance,
Kate
