If you've changed your spreadsheet, you may consider deleting your existing Range to add a new one.
Rather than deleting it, update your range instead in three simple steps:
1. Highlight your new range
2. Under Build, click on Reselect Range. Your range will automatically update.
3. Then click Fetch Data
With Reselect Range, ranges never need to be deleted - just updated.
If, for some reason, deleting a range is a must for you - tell our Product Team.
