如果按錯選擇，並且已經提交，可以更改嗎？ If I make a wrong selection and submit, can I change it?
可以。如需更改選擇，可於投票時間內在投票版面自行修改。 Yes. If you need to change your selection, please modify it on the voting interface within the voting period.
如沒有揀選任何項目下按”提交”，會出現什麼情況？What will happen if I click “Submit” without selecting any items?
如沒有揀選任何項目下按"提交"或沒有按"提交"，則會被視為棄權票。 If no selection is made before clicking the "SUBMIT" button or if the "SUBMIT" button is not clicked, it will be considered an abstention vote.
同一張選票，掃瞄多於一次，或多於一個人掃瞄，會否出現重覆投票？If the same ballot paper is scanned more than once or by more than one person, will there be duplicate voting?
不會。如重覆投票，只會計算最後揀選的選項。 No. In the case of multiple votes, only the latest selected option will be counted.
