[support] CCK and blank admin page

New to Drupal ... On Mac with MAMP just installed. I've installed the CCK module and am trying to install some of related modules. If I try to enable any of the following modules, my Administer page goes blank ... haven't a clue as to why. Link Node Reference Number Option Widgets Phone - CCK User Reference Zipcode - CCK Be gentle ... years ago, I had lots of experience with Cold Fusion on Windows, but none with PHP or LAMP/MAMP.
