Tabs, empty fields, etc, etc

So, i’m makeing a form in flash… and i don’t want that users can make “send” without all the text fields are filled, with an error message appearing if the user didn’t fill all the fields and press “send”…

:red:

I also would like to know hou to control the tab order in the swf, because when i press tab button, the cursor shifts between the text fields and the redraw regions, and i only want it to shift between the text fields…

Does anybody know how to do this???
