I added a tab to my worksheet, and the builder doesn’t show it. I went to add it under tabs, but it’s not on the list of available sources. I went to the data sheet, and clicked refresh sheet - the tab appeared for a second at the bottom, then disappeared.
Any ideas?
Unplug it and plug it back in.
Nope. Deleted it, added new, & refreshed sheet.The tab shows at the bottom for a second then disappears again. I should record it.
Try refreshing the browser, restarting it, restarting the computer. Just trying to eliminate a caching issue.
Did all that too. BUT - the threat of being recorded has suddenly made it work. 
Ha, you’re welcome. I seem to have that affect at work too. Things start to work when someone is showing me the problem. 
Yup, your kid’s arm quits hurting the minute you get to the doctor.
You had some data in the new sheet, I assume? At least a header row?
I did, yes.
