It looks like you suppressed the first extrude. RMB --> unsuppress
Craig (and Jody),
Thanks for the quick response. Both answers were right. I marked Jody's a correct because of the detail in the answer -- remember I am new to this -- helps to get pictures :-)
It looks like you suppressed the first feature (Boss-extrude) in your tree and every feature (cut-extrudes) after that auto-suppressed because they are dependent on the first feature. Ctrl + select the boss and cut features in the tree and then choose the option shown below to un-suppress them all.
