INJ files inject information into channels that already exist in the figure. Your file "Depress Calf Inner INJ.pz2" wants to inject information into a channel named "Depress Calf Inner". If that channel is not already present in the figure then the injection has no where to go.

 

{

targetGeom NAME_OF_EXISTING_CHANNEL

{

name YOUR_NAME_HERE

 

The first (internal) name must match an existing channel. The second (external) name can be whatever you want it to be. Poser works its ERC code on the internal name, the user only sees the external name.

 

Also it is probably best to have all the indices and Figure numbers set to one, currently they are set to five. Poser may be able to compensate for that and to be sure one would need to test it, but when I do it I stick with one.

Hope that helps.
