As I attempt to apprise everyone with my signature, doesn't work doesn't help. Neither does "I tried, but..."
It takes as little as a missing or misplaced character to cause a problem. The error number suggests you haven't drilled down to the proper level before attempting to apply something to it. The code itself is insufficient; we have to understand what the names apply to.
The more we hear silence, the more we begin to think about our value in this universe.
