Why is my label data not updating?
Double-check your spreadsheet columns.*Too Long Didn't Read
Once your label is setup perfectly you may import another spreadsheet and all of a sudden your labels won't update. What's up with that?
The answer is usually simple: the spreadsheet columns don't have the same name. Look at what variable names are used on your label design? Do they match with what's in the spreadsheet? Is the spreadsheet missing any columns that were in the original?
Like the old saying goes: trust, but verify!
