@rlopez -- thanks for the quick response. I guess I'm talking to the right guy, too! I tried it again in a fresh worksheet and got this error when I clicked Initialize the first time:
I have units set in my .mapleprofile, so I tried turning that off in the startup code for my test doc and still no go. I don't get this error message though. I've re-calculated the whole worksheet also.
I'm attaching my version, if you can glean anything from it. Do I need to remove units from my .mapleprofile?
I've got version 2017.3 also.
@rlopez -- I got the task working. I had to remove with(Units[Standard]) from my .mapleprofile code. I think this is a bug -- the task should work fine if units are installed. If you come up with a patch please let me know.
