Passing transformation parameters to an ETL Metadata Injection step

I'm working with the metadeta-detector discussed on Matt Casters blog here: http://www.ibridge.be/?p=273

There's a sub-transformation called 'Determine fields' that uses an ETL Metadata Injection step. The 'Determine Fields' transformation takes as input a filename, defaults to sales_data_sample.csv. It's supposed to pass this down to the injection step, but it's not. If I executed 'Determine fields' with another value for the filename ("test.csv") the injection step still uses it's own default filename (which is also sales_data_sample.csv, thus if you delete that file the trans will break).

How can I pass the filename down to the injection step? See attachment for relevant files.
