I think you need to prefix your variable names with *two* underscores, to make 
them indefinitely heritable down the succession of channels.  If they are 
prefixed with a single underscore, then they only get inherited *once*; so if 
the child channel spawns a grandchild, then any _VARS it inherited from the 
parent channel won't exist in the grandchild, but any __VARS will.
