Editing Records With Forms

Hi everybody,

I have a large problem which I can't figure out (well 2 actually but the other is less important):

1) I have a form which brings up the results of a search performed by the user (only contains some fields). From this list of results i would like the user to be able to a) see a full report of that Record (which I've done ok) and b) edit the data contained in that Record.

My results form opens the editing form no problems, however, i cannot edit any of the data contained within it. This only occurs when the results form is open as well so i guess it's because there are two instances of those fields open simultaneously. However, I am reluctant to close the results form because the results will be lost.

2) I've tried several methods to open the form at the desired record:
- using the WHERE condition argument of the OpenForm function
- creating a filter in the editing form that runs in the OnOpen event
These two require the creation of a variable (I'm using the Key field) that is inserted into these bits of code. However, all of my attempts thus far have been unsuccessful; every time it asks for the Parameter in a popup. I've defined the variable as a Public variable in a seperate module but don't really understand this aspect partcularly well; I'm obviously missing something.
- the form currently opens from it's own query that gets the Key Field Criteria form a hidden control on the results form.

Here is my code for the 'Edit' button:

Public stProjectID As String

'Results form 'Edit' button click:
Private Sub btnEdit_Click()
stProjectID = txtID2
[Forms]![frmResults].Visible = False
DoCmd.OpenForm "frmProjectEdit", acNormal
End Sub

'Edit' form open:
Private Sub Form_Open(Cancel As Integer)
Me.Filter = "ProjectID = stProjectID"
FilterOn = True
End Sub

Sorry for waffling on...

Thanks in advance for your help.
