Datefield and ComboBox inside a loaded MC

I am having an issue with the datefield and combobox components. I have created an swf with both units and they function correctly. The swf is then loaded into a holding mc on the main swf file using loadMovie. When this occurs both the datefield and combobox lose functionality. If anyone can give me some insight as to why this might be happening it would be greatly appreciated.

html one (datefield and combobox swf only)
html two (datefield and combobox swf loaded into holder swf)
zip (holder fla + datefield and combobox fla)
