I am very new to writing triggers and would appreciate any and all help.  I have searched the forums to no avail, I am unable to find any information related to this particular scenario.  I do not want to go the roll up summary field route.

I have a custom object (related list) on which I would like to prevent the deletion of a record if checkbox=true on the related Opportunity record.
