  3. Select Formula as the field type.
  4. Enter a formula that includes ISERROR in the formula editor.
  5. Click Confirm to save and review the formula field result.

Success Criteria

  • Interface result: A new formula field appears in the table.
  • Next action available: You can continue editing the formula and reviewing the calculated result.

Tips While Using

  • Common mistake: If you do not choose the Formula field type, you cannot enter a function expression.
  • Environment note: You need permission to edit fields in the current multidimensional table.

2. Enter ISERROR with the correct parameter format

Entry path: Formula Editor → Function Input Area

  1. Type ISERROR( in the formula editor.
  2. Enter the target value, reference, or expression that you want to test inside the parentheses.
  3. Check that the parentheses, references, and expression are complete.
  4. Save the formula and review whether the result returns TRUE or FALSE.

Success Criteria

  • Interface result: The formula editor shows a complete ISERROR expression.
  • Next action available: After saving, you can see the logical result in the field output.

Tips While Using

  • Common mistake: If the closing parenthesis is missing or the reference is incomplete, the formula may not calculate correctly.
  • Environment note: Different field types should match the formula expression you enter.

3. Use an example to complete an error check

Entry path: Formula Field → Formula Editor

  1. Create or select a formula field.
  2. Enter an example formula such as ISERROR(target_range) or wrap an existing expression with ISERROR.
  3. Save the formula and review the field result.
  4. Change related data and confirm that the result refreshes automatically.

Success Criteria

  • Interface result: The field returns TRUE or FALSE based on whether the target value produces an error.
  • Next action available: After source data changes, the result updates automatically.

Tips While Using

  • Common mistake: Using data that does not fit the current field setup can trigger other formula errors first.
  • Environment note: If the table uses collaborative content, refresh timing can depend on sync status.
