Access form combo boxes

[ninash]

Hi,

I have a form that has a combobox that is displayed when the ID for the question displayed in the form is reached.

My problem is that the combobox needs to display 3 different lists for selection for different questions.

I can trap the ID for the question and so display the combobox but I need help filling the combobox with data and ensuring that the list is cleared so when the next question appears it will fill with the list needed for that question.

If anyone can help Please do.... I need it

Thanks in advance
