Proc logistic-multivariate logistic regression

I am doing multivariate logistic regression with CGR and OBST as dependent varaibles. I used the syntax below. But I got the message that says that OBST is not found. I am using SAS enterprise. We can put 1 dependent variable in the dependent variable line. How can I put another dependent variable?

PROC LOGISTIC DATA=WORK.TMPMod
PLOTS(ONLY)=ALL
