If you need to do more than one comparison, Select - Case - EndSelect, is a much better way to do it.

Code:

Select
 Case INGROUP("ITDEPT") = 1
  USE T: "\\SERVER1\APPS"

 Case INGROUP("FINANCE")= 1
  USE P: "\\SERVER3\ACCOUNTS"

 Case INGROUP("SURPAC USERS") = 1
  USE G: "\\SERVER9\DATA"

EndSelect


You may want to also look at what the errors are thereby giving you an idea why they are not mapping

Code:

 Case INGROUP("ITDEPT") = 1
 ? "InGroup error: "@error
  USE T: "\\SERVER1\APPS"
  ? "Use Error: "@error
