Input text fields change colour when entered - great but what if....?

I am uploading a file with input text field that changes colour when you click in it - this is great, but what if i wanted the following:

in the initial state, the text box is grey as you can see, but when i click inside it, it fades to pink instead of suddenly just changing to pink. And likewise, when i click outside the box it fades back to grey.

You will see what i mean if you view the file.

it’s mx not mx2004

Don’t know if this would be better in the actionscript forum, but well it’s here. :slight_smile:
