Compare two arrays

I have two arrays filled with inventory part numbers and pricing information.

Dim existing400(2000, 4)  ~600 items
Dim New400(2000, 3)      ~1200 items

existing400(1,1) 'part number
existing400(1,2) 'Item description
existing400(1,3) 'unit price
existing400(1,4) 'unit price from "New400" array

new400(1,1) 'part number
new400(1,2) 'Item description
new400(1,3) 'unit price

What I am looking to accomplish is to fill the first array(existing400(1,4)) with the current pricing from the second array(new400).  

I need ideas on how to set this up.
Thanks,
Bob

Try this:

    Dim I As Long, J As Long
   
    For I = LBound(existing400) To UBound(existing400)
        For J = LBound(New400) To UBound(New400)
            If existing400(I, 1) = New400(J, 1) Then
                existing400(1, 4) = New400(1, 3)
            End If
        Next
    Next

rettiseert,
Found a opps but I was able to fix it.  

existing400(1, 4) = New400(1, 3)
Should have been.
existing400(I, 4) = New400(J, 3)

Works great.
Thank you.
Bob

yes, a little mistake : )

also, you would like to add a
exit for
after the existing400(I, 4) = New400(J, 3) line
