Use conditional logic to show/hide an administrative field [RESOLVED]

I have a button in an HTML field on a form. I want to hide it from the user but show it to an administrator. There is also an administrative field into which an administrator will put some text. I tried hiding it until the administrator makes a change to the text field but administrative fields do not show up on the drop down as a possibility in the logic. How do I do this?

Hi, you may want to use a User rights plugin.

That is what I did. Works great.
