I have a code to check for a duplicate in column B7 and downward. I need to somehow configure it so it finds a duplicate in row B7-downward AND C7-downward. Here's the kicker... I need it to be like an "AND" function. It will be OK if the unique ID's are duplicated in column B as long as the unique ID is not duplicated in column C.

[TABLE="width: 500, align: center"]
<tbody>[TR]

Just imagine a userform that has a drop down list... One for the 3 letter acronyms and the other for A, B, C. Before it can make it onto the sheet... I want the userform, when trying to hit submit, to prompt you that you already have an OAK A on the list, please choose something else. Here's my code already...

Code: 
Private Sub cmdSubmit_Click()


If cmbLH = "" Then
    MsgBox "The Line Haul name cannot be blank. Please choose a valid Line Haul name for the run that you would like to add.", vbOKOnly, "Invalid Line Haul Name"
    Exit Sub
Else: End If

If cmbOrig = "" Then
    MsgBox "The Origination Depot cannot be blank. Please choose a valid Origination Depot selection for the run that you would like to add.", vbOKOnly, "Invalid Origination Depot Name"
    Exit Sub
Else: End If

If cmbDest = "" Then
    MsgBox "The Destination Depot cannot be blank. Please choose a valid Destination Depot selection for the run that you would like to add.", vbOKOnly, "Invalid Destination Depot Name"
    Exit Sub
Else: End If

If txtDrivStart = "" Then
    MsgBox "The Driver's start time cannot be blank.  Please fill out before moving on.", vbOKOnly, "Invalid Driver Start Time"
    Exit Sub
Else: End If

If txtLoad = "" Then
    MsgBox "The Load Ready to Depart Time cannot be blank.  Please fill out before moving on.", vbOKOnly, "Invalid Load Ready Time"
    Exit Sub
Else: End If

If txtDep = "" Then
    MsgBox "The Actual Departure Time cannot be blank.  Please fill out before moving on.", vbOKOnly, "Invalid Actual Departure Time"
    Exit Sub
Else: End If

If txtSeal = "" Then
    MsgBox "The Seal No. cannot be blank.  Please fill out before moving on.", vbOKOnly, "Invalid Seal No."
    Exit Sub
Else: End If

If txtDate = "" Then
    MsgBox "The Date cannot be blank.  Please format the date as mm/dd/yyyy.", vbOKOnly, "Invalid Date"
    Exit Sub
Else: End If

If txtName = "" Then
    MsgBox "The Driver's name cannot be blank.", vbOKOnly, "Invalid Driver Name"
    Exit Sub
Else: End If

If txtTruck = "" Then
    MsgBox "The Truck Number cannot be blank.  If TPC then type TPC", vbOKOnly, "Invalid Truck No."
    Exit Sub
Else: End If

If txtTrailer = "" Then
    MsgBox "The Trailer Number cannot be blank.  If driving a bobtail then type N/A.", vbOKOnly, "Invalid Trailer No."
    Exit Sub
Else: End If

If cmbTPCName = "" Then
    MsgBox "The TPC selector cannot be blank.  If it is not a TPC then choose N/A.", vbOKOnly, "Invalid TPC Selection"
    Exit Sub
Else: End If

Sorry I don't think I understood the question fully, but was just thinking:

Would it help if you concatenated those 2 columns somewhere else to create a single unique ID and just copy that formula all the way down the page? eg Column G =B7&C7 or OAKA, and then just hide that column so you don't have to look at it but can still reference it in vba

Basically I want a code that references the cell next to eachother... A1 and B1. If it sees it's OAK in A1 and A in B1 then the userform won't allow me to submit the two comboboxes of OAK and A, it must move onto OAK and B. I don't know if it makes sense. I don't know how to write a concatenated VBA Code. I know it's with the ampersand key and can use it in a worksheet function on sheets, just don't know it in VBA.
