When staff go to add an entry, things will look as it does when there are no calculated values as default. The PagePart appears the same and staff will click the Add New Item button.
When staff create a new entry for a list that has a calculated value as default value column, the column with the calculated value will auto-fill.
Adding a new entry to the list with the calculated value created earlier, [Today]+30, the form automatically fills the date to 30 days from Today. This feature can help reduce mistakes and speed up daily logging as individual staff are not having to do any calculations themselves.
Note: When a Default Value is set as a Calculated Value, the value can be changed. For example, if the Next Check In date needs to be changed, the staff person can enter a different date.
