How to show a certain code to certain groups

[BostonBob]

Hello,

I want to show a certain line of code to only certain groups in the header.  What would be the best way to do this?

<script type="text/javascript" src="/.../....php" charset="utf-8"></script>

This is a demo code I want to incorporate, however I only want to allow certain groups to have access.

Thanks,

BB

Anyone?
