Shock decomposition with calibrated model syntax

Hi all, I am trying to use shock_decomposition command with a calibrated model to reproduce what I have obtained after the estimation. I believe I have written it in correct syntax but I still get following error message:

Error using shde_symmpar_ST_trend_noCT_AP.driver
Error: File: driver.m Line: 1303 Column: 28
Incorrect use of '=' operator. To assign a value to a variable, use '='. To compare values for equality, use '=='.

Error in dynare (line 281)
    evalin('base',[fname '.driver']);

Error in shde_main (line 12)
dynare shde_symmpar_ST_trend_noCT_AP

The shock_decomposition command works well after the estimation command. I do not know if I have not yet understood the syntax correctly or it is a bug.

I am working with Dynare 5.0. Please check the attached codes to reproduce the error message.

Thanks in advance. (835.7 KB)

There is a typo: shock_decompostion should be shock_decomposition

Thanks Johannes! Such a silly mistake.
