Simultaneous use of Multiple shocks

Hi
I am using the matlab simult function to trace the impact of multiple shocks simultaneously. For defining initial states, I am getting it from oo_.dr_ys.
However the vector oo_.dr_ys doesn’t show one particular variable. Whenever I declare that variable, it shows one less.
can anyone suggest a way to resolve this? Thank You

Sorry, but I don’t understand the problem.
