It would help to see the syntax of the command before margins. But in 
any event, your syntax implies that lntotalexp is a factor variable, 
which is not what you want. As the help for margins says,

        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.  The variables may be typed 
with or without the i. prefix, and you may use any factor-variable syntax

You are including lntotalexp in the marginlist and you should only do 
that for factor variables.
