Rejecting Reversed Shopping Dates

Reversing two dates is a form-entry mistake, not a reason to lose the list already being built. The existing household item makes it clear whether the failed calculation leaves prior work intact.

A list already contains a manual 1 each Dish soap line. The cook sets the last date before the first.

Try the reversed date range

1. Create the manual household line.
2. Enter a future first date and a last date one day earlier.
3. Calculate meal needs and read the error.

The original item is untouched

The range is rejected and the manual item remains.

The calculation requires a valid first-to-last date order. Correcting the range is necessary before generating meal needs; the error does not replace or clear the manual shopping line.

Review the range after switching between months in the date picker.
