A Baseline DSGE Model-----an error

The model is based on the Baseline DSGE model of Jesus Fernandez.And I add three equations ans three variables.there are the following errors.

You did not declare endogenous variables after the estimation command.

You defined yd_f as an observable, but the variable in the data-file is named y_f.
