If the target field is not a text field, a type conversion takes place. If that conversion results in a different value than the provided one, an error will occur. You may allow lossy conversion by checking the switch.
A protection level has to be selected from the Protection menu of the main window (ARB_NT/Protection) equal or higher than that assigned to the selected alignment (ARB_NT/ali_*; third broad rectangular button in the upper part of the main window).
Except for the 'name' field (the identifier), there are no different protection levels for different fields. Take care not to write to fields which should contain unique entries for the corresponding species/genes such as accession numbers.
