<img src="/uploads/upload/image/5200/direct/1580240795911-1580240795911.png" alt="Diagram showing [NA] missing value indicator transitioning from visible to hidden. Left side shows blue square with white [NA] text, orange arrow labeled 'automatically' points to right side showing lighter blue square with white [NA] text, illustrating the automatic hiding of missing values." style="text-align: center;" class="fr-fic fr-dib"> Copy and paste the code below in "Pre-calculate." Hit save. Your project will now open with \[NA\] not showing by default. Typically, the Protobi default is to "showMissing" : true. The code sets showMissing to be false on opening of the project. ``` if (typeof protobi !== 'undefined') { protobi.viewModel.set({'showMissing': false}) } return rows; ```
