Run Code When Clicking Locked Cell

I have programmed a Form in VBA that initializes by clicking a button on a worksheet. The Form features combo boxes, text fields, and a couple option buttons. Once completed, the Form enters the values entered by the user (as strings) in contiguous colums in a single row. The worksheet is locked so as to not allow users to input values into the worksheet directly and bypass the Form.

The question:
Once a row is filled by submitting the Form, i want to allow a click event on that cell (like double-clicking, for example) to pop-up the Form, but containing the corresponding values from the cells in the matching combo boxes, text fields, option buttons. I want to do this so that I can allow modification on a row without letting the worksheet be modifyable without passing through the Form. Here's the code for submitting the Form values into the worksheet:

Private Sub cmdSubmit_Click()
ActiveWorkbook.Sheets("ALTEC Growth Report").Activate
Range("A7").Select
Do
If IsEmpty(ActiveCell) = False Then
ActiveCell.Offset(1, 0).Select
End If
Loop Until IsEmpty(ActiveCell) = True
ActiveCell.Value = Trim$(txtName.Value)
ActiveCell.Offset(0, 1) = cboCC.Value
ActiveCell.Offset(0, 2) = cboProdServ.Value
ActiveCell.Offset(0, 3) = cboStatus.Value ..................
