RegularExpressionValidator is failing...how to cap it at 20 characters

[Coder76]

Hi. I have a regularexpressionvalidator that should meet these requirements when a user enters a password:

-- Must be be 8-20 characters
-- Must include at least one uppper case and one lower case letter
-- Must include at least one special characters (~ ! @ # $ % ^ & *)

Here is what I have for my validationExpression:

^.*(?=.{8,})(?=.*[a-z])(?=.*[A-Z])(?=.*[\*@~!#$%^&]).*$

The problem is that it does not cap the password at 20 characters. How can I make it do this? Thanks you in advance for your help!
