Why don't you use the heckman command which takes care of the selection and correct the standard error in your second step equation?

	I have generated a selection term in stata to correct for
	schooling sample selection in earnings regressions.  As the inverse mills
	ratio is a generated regressor, I would be most grateful if you would show
	me how to correct the standard errors
	to take account of this.
