SPSS: How to use the create dummy variable tool?

Hi everyone,

I am new to SPSS (I am using SPSS 22). I need to convert a set of 300 categorical variables into dummy variables and was advised to install and use create dummy variables tool.
I tried to convert all the categorical variables at the same time, using "to":
However the results did not appear. There was an error of " invalid variable or TO usage". Could you please advise me how I could convert this large number of categorical variables to dummy at once by using this tool?

Thank you very much!
