Keypad-keycode verification

Hi guys, I’m stuck, please help…

I’m creating a keypad which uses buttons to enter numbers into an input textfield.

I can get the buttons to enter numbers into the field but can’t figure out how it knows the code is correct.

I’ve attached the fla to explain what I mean.

Code used so far:

On button 1:
[INDENT]on (press)
{
this.number=‘1’
}

on (press)
{
_root.code.text+=this.number;
}[/INDENT]

on the Submit button:
[INDENT]on (release)
{
if (code == “111”)
{
gotoAndStop(10);
}

else
{
gotoAndStop(1);
}
}[/INDENT]
