Updating Sub Forms Access mdb

Hello,

I am actually asking this question on behalf of a friend, personally I would rather trap my manhood in a tube train door and get dragged along for 24 hours than use VBA :p

Now that I have made it clear that I detest VBA maybe you wont be so hard on me for asking what could be a really retarded question.

In the database there is a form with a tabbed control. In one of the tabs a subform has been made using the access wizard. When the record is changed on the main form some of the details change on the sub form but it doesnt execute any code. For example, my friend checks the values in one of his fields on the sub form to see which checkbox he needs to tick. This is done in code but I cant find a procedure that is called in the sub form when the main form record is changed. Is there such a thing, and if not how would I get around this problem? :sick:
