Dear Stata users,

I am running a probit model with three binary indep. vars. and some other continuous dep. vars. The probit model runs perfectly, however, whenever I want to take the margings (which I only want for the three binary Independent variables), Stata tells me that the "Factor was not found in the list of covariates". I posted the log below. The variables I want the margins of (
drought_025 MMdrought_025 MM_use) are three binary indicators. What can I do to fix this?
Best, Anne
