Input Text Boxes in MovieClips, Can't Type Into Them

Hello,

I have created some input text boxes inside a movieclip that tweens onto the stage when the user clicks a button.

Once I have clicked the button, when I hover over the text boxes I get the “carret” mouse pointer but I cannot type anything.

Anyone know the problem?

Thanks,

Blekk.

P.S. Sorry for the brief description, I am in a hurry.
