Dim i As Integer
Dim Str As String, c As String
Dim falpha As String, fnumeric As String
falpha = ""
fnumeric = ""
For i = 1 To Len(Str2)
    c = Mid(Str, i, 1)
    If IsNumeric(c) Then
        fnumeric = fnumeric & c
        falpha = falpha & c

pls try

Function FindNumber(MyString As String) As Double
strFormula = "=1*MID(A1,MATCH(TRUE,ISNUMBER(1*MID(A1,ROW($1:$256),1)),0),COUNT(1*MID(A1,ROW($1:$256),1)))"
strFormula = Replace(strFormula, "A1,", Chr(34) & MyString & Chr(34) & ",")
FindNumber = Evaluate(strFormula)
End Function

Simply because I couldn't pass up this question without giving a Regular Expression answer:
Function ExtractNumber(str2 As String) As String
 Dim RegEx As Object
 Set RegEx = CreateObject("vbscript.regexp")
 RegEx.Global = True
 RegEx.Pattern = "\D"
 ExtractNumber RegEx.Replace(str2, "")
End Function

Open in new window

It will return whatever numbers are in the string, regardless of what is sent:
 Debug.Print ExtractNumber("B2")
 Debug.Print ExtractNumber("C3")
 Debug.Print ExtractNumber("DE45")
 Debug.Print ExtractNumber("B2  C3   D34   B21   AC3    DE45")
