I 'thought' that my reply would appear threaded within the discussion I was reading (https://lists.gnu.org/archive/html/discuss-gnuradio/2013-02/msg00336.html) my apologies for any confusion

This was a very helpful introduction to hierarchical blocks.  One thing I am unclear on is how a parameter in a hier block is controlled via the top block.  For example suppose I have a moving average block inside my hier block and I want the number of averages to be defined from the top block.  Within the hier block I have a parameter block with the ID 'avgLength' and the moving average block has a length of 'avgLength' and a scale of '1.0/avgLength'.  How do I pass the value of avgLength from the top block into the parameter of the hier block?

Thanks in advance for any replies.
