Hi there!


Answering n.1 - If you want just numbers in your phone text field then just select the range of the characters allowed to be typed in the field. (In the imput text properties, you will find a button named "characters...", hit "Specify Ranges" and then click "Numerals[0..9]..." then hit OK.

Answering n.2 - This is a bit more complicated. You can set any verifications but still you can't prevent from a wrong imput.

on(release) // simple button action
{
    if((email.text.indexOf("@") == -1) or (email.text.charAt(0) == ".") or (email.text.charAt(0) == "@") or (email.text.indexOf(".") == -1))
    {
        trace("Wrong email format.")
    }
}

Here the email field can't start with "." or with"@" and must have both along the string. This is enuf to make you imput an correct email format. Again, this won't prevent users from type "damn_email@verification.com" with im pretty sure doesn't exist :)

Thats it. Anything just gimme a call
