Question : subform totals

I have a subform, which can have multiple rows  for Providers.  In the provider rows there is a field called "Originalbill".  I want to sum of OriginalBill and place it on the Main Form.  I have added in the footer of the Subform :   =sum[OriginalBill] and then reference that text box on the main form.  THe problem I am having is that when I have more than one provider row on the subform, the total on main form only shows one of the rows totals?   It does not sum all of the rows ?

Any help?

Answer : subform totals

ahh so.  Well, that's most likely the issue.  If you are using any new features in A2007 not in A2003, then I suspect this is the problem.  

We need someone with A2007, however I'm going to finally load A2007 on another laptop this weekend.

Sorry ...
