listbox visible if a certain character is contained in a nother listb

[tamnet]

I am trying to have a listbox either visible or invisible based on wether another listbox value contains the letter "d", I have tried to write the following function without success and wondered if someone would take a look and perhaps steer me in the right direction

<script language="javascript">
function ToggleListBoxDisplay(){
var lstFlute=document.getElementById("lstFlute")
if Right(lstFlute.value= "d")
  lstMiddle.visible = true;
else
lstMiddle.visible = false;
}
</script>

I then call the function like this

onChange="ToggleListBoxDisplay()"
