    Scan through a word and adding numbers of each letter

    So I have a table that has a corresponding number for each letter. I what the user to supply a text word - say 'MSACCESS'.
    I would like for the query to scan the word and add up the following for the letter number assignment table (tblTEXTNUM) example

    M = 1


    S = 2
    A = 3
    C = 4
    E = 5

    so M + S + A + C + C +E +S + S or 1+2+3+4+4+5+2+2

    equaling and returning the sum of 23 at the end


    TIA

    Create a VBA function that loops through the characters in the input (For/Next loop using the Len() function). For each letter, use a DLookup or recordset to get the associated number. Accumulate that in a variable and do what you want with it at the end.

    A query alone won't accomplish this. Build a public VBA function that can be called from query or textbox. Like:

    Code:
    Function SumLetters(strL As String) As Integer
    Dim x As Integer, rs As DAO.Recordset
    Set rs = CurrentDb.OpenRecordset("SELECT Letter, Num FROM tblTextNum")
    For x = 1 To Len(strL)
        rs.FindFirst ("Letter='" & Mid(strL, x, 1) & "'")
        SumLetters = SumLetters + rs!Num
    Next
    End Function
    
    What is the reasoning for these letter/value assignments - why is M = 1, etc?

    It's exactly the type of homework I've had to do for my C# class.

    Okay, so why are the Num values repeated?

    If this is just a school programming assignment and reason for number assignments is not important, ignore question.

    Does the code do what you want?
