Hi StataList.

How can I use the browse command to display certain observations from four specific waves of data (panel data)? When I enter the following, the br window is empty.
Code:
br xwaveid edlev empstat marstat if wave==4 & wave==7 & wave==10 & wave==14
My error is surely in the 'if' part of the command, so any help is kindly appreciated.

Best, Chris
