One mistake I can see is that the "drop" message of the inventory takes 
an index, not an object name. You can also leave out the argument 
entirely, it will then automatically assume state.inventory.carried. See 
nodes 9 (use of the key from the inventory in a similar way to what 
you're trying to do) and 50 (inventory) in the demo project.

If as you say you don't even get that far because 
state.inventory[state.inventory.carried] == "TVCable" is never true, 
then I would suggest inserting
pipmak.print(state.inventory[state.inventory.carried])
or examining state.inventory using the table inspector from the Lua 
command line to find out what it is.
