Flash 8 / PHP Email / Tab Order

Ok, have a weird one here. My PHP works great, Flash emails correctly and all that. The problem is that my tab orders are all screwed up. If I place the code,

onEnterFrame = function(){
full_name.tabIndex = 1;
company_name.tabIndex = 2;
email_address.tabIndex = 3;
phone_1.tabIndex = 4;
phone_2.tabIndex = 5;
questions.tabIndex = 6;
}

then tabbing works, BUT I lose the ability to type in my input boxes. The only way to make this tabbing work is to give my boxes an instance name, for Flash, but they also have a var name to send the variable to PHP. When I use both an instance and var name, my input boxes are populated with ā€œ_level0.contactUS_mc ā€¦ā€ blah blah. If I remove the instance name, then tab orders are all screwed up.

I have attached the source from the tutorial: http://www.kirupa.com/developer/actionscript/taborder.htm

You will notice the input boxes have stuff in them. But if I remove the var name, then it works, BUT if I remove the var name, then how do I send that information to PHP?

Thanks.
