Accessing Data From Other Forms

Hi

i have a slight problem. In my tool i'm creating, i have a workproduct form and a button that takes me to another form that allows me to enter in defects to that work product (which works). The thing is, if the defect is found in a 'coded' work product, some fields will appear for new data, and other fields will disappear. On the work product form, there will be a field that displays if the work product is code or not (taken from a table) and the fields that will appear (and disappear) are on the defect form. I want the tool to look on that work product form to see if the 'phase' field is 'code', if it is, then show/hide fields on the defect form. Heres my way of interpreting what i want in code form. I hope you can gather whats going on from this:

Private Sub Form_Open(Cancel As Integer)
If !Form.preMeetingForm2.phaseName = "Code" Then
lineNumber.Visible = True
lineNumber_Label.Visible True
function2.Visible = True
function_Label.Visible = True
page.Visible = False
page_Label.Visible = False
section2.Visible = False
section_Label.Visible = False
End If

Note: this Form_Open event is on the defect form (where the fields will appear and disappear)

Thanks in advance :)
