Compiler error in one sketch, but not another?

The first reply hit the answer. It wasn't a bulls eye but was in the black. The method does work. Though I suppose I could have (should have) at least asked a question, like "what the heck does this error mean?". :smiley:

Maybe you are right, if I had thought to word it exactly that way. Hindsight is 20/20. Anything less would have lead to the short answer (non-root cause) answer or to wandering discussions of irrelevant items.

I'm sorry to say, but there is a very critical tipping point around here (a very fine line), between too little and too much information versus getting constructive and useful responses. It is easier to supply more information on request, then to get folks to focus on the problem and relevant information.
