How can I populate a combobox after FCKeditor has loaded?

Bump

Anybody?

Here's what little JavaScript I have in my page:

function populateDataFieldDropDown() {
entityTypeID = document.getElementById('ddlEntityTypes').value;
processID = document.getElementById('ddlProcesses').value;

var editor = document.getElementById(FCKeditor1');
}

I'm unable to get anything related to the toolbar or my combobox from the editor object. Am I looking at the wrong object?
