Looks like a fundamental understanding problem.
$1 and $2 within a function refer to the parameters supplied to that function. They are not the $1 and $2 parameters provided to the main script.
The convention for a function called "usage" is to just output a message telling the user how to correctly use the script. It is also conventional to "exit" the script if there is something wrong.
You would be best testing the number of parameters $# in the main flow of the script and calling a "usage" function if the number of parameters is incorrect. If you then do more validatation you then have available a general function to report the error.

lmfsetup
lmfsetup(8) System Manager's Manual lmfsetup(8)
Name
lmfsetup - License Management Facility PAK registration script
Syntax
/etc/lmfsetup [ template ]
Description
The script allows you to register data supplied by a Product Authorization Key (PAK). The script prompts you for the data associated with
each of the fields on a PAK. When all the data has been entered, the License Management Facility (LMF) ensures there are entries against
all the mandatory fields, and that the Checksum validates all the license data. If the data has been entered correctly, the PAK is regis-
tered in the License Database. If the data has been entered incorrectly, the appropriate error message is displayed and you are given the
opportunity to re-enter the data.
The template option allows you to register license data from templates in A template containing a partially complete PAK is created by some
products as part of their installation process. The script only prompts you for data on the fields that are empty in the template. If the
script cannot find the specified template in it searches the current directory.
The script is provided as an alternative to the command. This displays a template, which includes the fields on the PAK, and invokes an
editor so that you can add the license data to the appropriate field. The command also allows errors to be corrected without having to re-
enter all the data.
