I don't think you are understanding what -margins- does. Look at the
help and you will see that it starts
margins [marginlist] [if] [in] [weight] [, response_options options]
where marginlist is a list of factor variables or interactions that appear
in the current estimation results.
So, you are offering
tfhhh shg lntotalexp ...
to -margins- as a marginslist. My interpretation is that -margins- is
happy to accept -tfhhh shg-, whatever they are, as part of a
marginslist but bails out because -lntotalexp- is certainly not
Otherwise put, it's not enough that your syntax looks like what
Carsten was using as an example. It must also make sense to -margins.
Also, you really must read the help!
