Problem updating calculated control

[theOnlyMontego]

I have a form in continuous form view with three calculated controls in the footer: TaxTotal, GrandTotal, and MaterialTotal. Each one of these controls is assigned a value via a function. The functions get the information from the records in the body of the subform. When I change the data in the subform, it takes one extra event to update the calculated controls. Is there a way that I can fix this to update the controls in real time without having to initiate some event to force the update? Any advice would be appreciated.

Oops, the controls are run off of sum functions, it's my price field in the main body that gets it's value from a function and the calculated controls get values from that field.
