When invalid data is entered, which type of message box shows to alert the user?
(A) A yellow triangle
(B) A red X
(C) A wavy blue underline
(D) An orange X
When you set up a warning alert box in software such as Microsoft Excel for bad data entry, it shows a yellow triangle with an exclamation point. The message lets the user know the input fails validation rules. Users can still continue if they skip the warning. (This helps avoid errors in spreadsheets.) This approach keeps entries from being rejected outright. The system allows editing without stopping workflow.
