I am having trobule with the setValue() not working for a combo box.

Here is the code that I'm using to test it..

function getValueOfItem() {
valueOfItem = listINVENTORY.getValue();
statusMessage = 'getValue..';
}

function setValueOfItem() {
listINVENTORY.setValue(valueOfItem);
statusMessage = 'setValue..';
}


The two functions above are attached to buttons. I select a value
from my drop down, click the button attached to the "get value" function above, change the value of the drop down and then click the button attached to the "set value" function above. I know that both functions are being called because the status message updates, yet the combo box does not..

What's the deal?
