Impulse responses

[Carmangella]

Hello,

I'm new in Dynare and I need to simulate impulse responses in this model. I try to write:
shocks;
var e_a_eur = sigma;
end;
(as you can see in attachment),

but this doesn't work well. I tried it for just the EU productivity shock, but I need to get six figures: EU, US productivity shock, EU, US cost-push shock and EU, US monetary shock. Do you have any idea how to do that?

Thanks for help!
