Ensure Code Understands Object It Should Relate To

I have written some code that copies certain cells from a spreadsheet constructed form back to a master spreadsheet database. The idea being to prevent users of the form from accessing the database and mucking it up. I write it the long way round and am now trying to modify it to not have to open and close the database everytime BUT whenever I change it I get errors that I think relate to the code not understanding the change of object...

' 3. send updated data to the database (all yellow boxes will update)

' set parameters for cells to copy from
Dim r As Long, e4 As Long, e6 As Long, e18 As Long, e20 As Long, e22 As Long, e24 As Long, _
e26 As Long, e28 As Long, e30 As Long, e32 As Long, e34 As Long, e36 As Long, e38 As Long, _
e40 As Long, e42 As Long, e44 As Long, e46 As Long
r = Range("D2")
e4 = Range("B4")
e6 = Range("B6")
e18 = Range("B18")
e20 = Range("B20")
e22 = Range("B22")
e24 = Range("B24")

The little blocks of code go on for 17 open/closes!
