ActionScript 2.0 :: Displaying XML Value In Flash

I'm having trouble setting the value of a dynamic text field (elevation) equal to a value from an external XML source.

Here is a snippet of the XML source:
<?xml version="1.0" encoding="utf-8"?><WeatherReport xmlns:xsd="[URL]">
<station>
<elevation>6</elevation>
</station>
[Code] .....

Then I try to set the dynamic text field "elevation" equal to the "elevation" value in the XML using the following code, but nothing happens:
function displayResults() {
elevation.text = airportXML.WeatherReport.station.elevation.text}
