Thank you Bill. I was not reading the word Macro in the error literally enough, and was translating it into a more generic meaning: function, which all the codes really are. With your information I did find that the macro #6 was missing, so I recreated it with the commands you listed. It is now working.
I suspect that I accidentally deleted the macro when I was poking around.
Since you were so helpful with this problem, do you have any idea why the Handibot generally (>50% of the time) does not reconnect to my wifi network when rebooted?
My procedure currently is to go out to the barn with a laptop or tablet, connect to the Handibot network, switch it to my wifi network (providing it the password each time), and then walk back to the house to program it, the walk back to the Handibot to activate the job. I have gone so far as to point a high powered directional antenna at the Handibot (no walls or trees in the way) to ensure it has a perfect signal (the Handibot seems to have a weak antenna relative to my laptops and tablets). It would be really nice to be able to not need to walk back and forth so much.
Other than these few minor hiccups, working with the Handibot has been a real treat.
Thank you.
