Answer : Can a Lookup column be used in a calculated column

You can use a lookup column in a calculated one if you do a workflow saing if the lookup column in different then zero (example) set a certain field to the lookup column value.
I've tried the trick with the "Empty" column and it was displaying the field's ID rather than the field itself.
