Hey,

You are such a great help to me! If I can answer any questions I will!

I have again a small problem. I’ve got a dynamic textbox “name” and simulated a keyboard in flash. If you click on the button which says A the action will be:

on(release){  
name=name+“A”;  
}

The problem is that I want such a button simulation for backspace, so the last key pressed wil be erased. I want to keep it simple and don’t want to use arrays. (though it isn’t that hard ;)) I know that the keycode for backspace is 8 but if I use it an eight will be added to the variable.

Please help me out 🙂  
Thanks in advance,
