move to new record in subform, acess 2007

[ravderic]

I have a main form "Customer Service" with a subform "Invoice Items Detail". I open a popup form with a button on the main form and add data to the subform. I use SetValue actions to input my values. It works but I can not go to a new record in the subform it just keeps writing over the data in the same subform record. I tried using GotoRecord, New and get form is not open error. I've opened the form hidden and tried. No luck. I’ve tried so many different approaches to this problem it’s all becoming a blur. I’m new to access programming so any help would be appreciated.
