Thanks donnena for your help on this. The M4 Child Dial read me said that you needed to expand the parameter dial options to reveal the hidden values by clicking on the white arrow or right clicking before loading the product. Otherwise it wouldn't work. When I did this the unhide option was absent. I subsequently googled the issue and found a Poser forum on Daz where the same problem had been discussed. Apparently some versions of Poser do have the unhide option (including some old ones) but some don't and that includes Pro 2012. This Daz forum suggested downloading the script and gave links which is what I did. As I say when I run the script I get the two columns as shown in the freebie description but I'm not sure what to do next. The parameter dials do not show the hidden values.
