10 ticked checkboxes before alert appears

I'm not very familiar with javascript and I have been trying to find ways on how to do this.

I have a checklist with 5 sections.

After a selected number of boxes have been checked, say 10 boxes ticked under section 1, I would like to put an alert saying that they have completed section 1.

Is there a way to do this with checkboxes?

Or is there a more efficient way of doing this in livecycle.

Your help will be greatly appreciated.

Regards,

Marie
