Put your Forms inside of a ViewStack container. You can then bind the ViewStack's selectedIndex to the selectedIndex of your ComboBox:

<mx:ComboBox id="comboBox" />

<mx:ViewStack selectedIndex="{comboBox.selectedIndex}">
    <mx:Form id="formA">
        ...
    </mx:Form>
    <mx:Form id="formB">
        ...
    </mx:Form>
</mx:ViewStack>
