Hi Darren,
Here's a function that'll help.

Function NumbersOnly(T)
    'VChas remove characters/spaces and just give us the numbers
    Dim K, Result
    If IsNull(T) Then
        NumbersOnly = Null
        Exit Function
    End If
    For K = 1 To Len(T)
        If Asc(Mid(T, K, 1)) >= 48 And Asc(Mid(T, K, 1)) <= 57 Then
            Result = Result & Mid(T, K, 1)
        End If
    Next
    If Len(Result) = 0 Then
        NumbersOnly = Null
    Else
        NumbersOnly = Result
    End If
End Function

Hi Guys
I'm trying to comparing phone numbers and report dupes. 
 
Basically I get a user to enter a phone number - then check if it is already
in the dB If it is then I go to the record that already has it.
 
But of course people legitimately put in spaces after area codas and after
the prefixes.
So it becomes tricky to compare
 
eg 01 1234 5678 is the same number as 0112345678 but a simple dlookup won't
catch it
 
So I wanna remove all the spaces so I am comparing at least the same
'number'
 
OR
 
Do any of you have a method for comparing or routing out dupe phone
numbers??
 
Many thanks in advance
 
Darren
