title: Get corresponding items from a selected listbox item
body: <p>As the title says, Once I select an item from lstordpizza, the corresponding item from lstordserving and lstordqty will be shown from the comboboxes shown in the image. Any help would be appreciated. :)</p>
  
  <p>EDIT: Sorry for the lack of info to my post and I can't think of any way to do this.  </p>
  
  <p>When I select 'Hawaiian Supreme', the corresponding item which are 'Family' should appear in the combobox as well as the quantity '9'.</p>
