I need help debugging my code. It does everything I need it to do but for the UID, the criteria needs to be that the UID can only be valid if the text entered has an uppercase letter, lowercase letter, and a number and is between 8 to 12 charaacters long. Right now it will give me a valid response if I either have all lowewrcase letters and a number, or all uppercase letters with a number. It will also give me a valid response for uppercase, lowercase and a number which is what I want, but that is not the only way it will produce a valid response I need it to show invalid if there are all lowercase letters and a number and also invalid if all the characters are all uppercase and has a number as well.
