    Unanswered: Stumped on Expression

    I am searching the forums for various answers to this or that I am trying to do with a database in Access 2k. I know a bit of expressions or formula from excel and I am seeing examples of expressions like

    Replace(fieldname,"","")

    when I try this formula in a query I get the error:

    undefined function 'Replace' in expression

    I get the same error with Substitute

    I know whatever I am missing must be simple, whats wrong with this picture?

    As far as I know, Access will not take Substitute. Are you sure you have Access 2K? Replace won't work in Access 97.

    Hope this helps.

    I'm working with XP and found this in the VB help files.

    Replace Function


    Description

    Returns a string in which a specified substring has been replaced with another substring a specified number of times.

    Syntax

    Replace(expression, find, replace[, start[, count[, compare]]])

    The Replace function syntax has these named arguments:

    Part Description
    expression Required. String expression containing substring to replace.
    find Required. Substring being searched for.
    replace Required. Replacement substring.
    start Optional. Position within expression where substring search is to begin. If omitted, 1 is assumed.
    count Optional. Number of substring substitutions to perform. If omitted, the default value is 1, which means make all possible substitutions.
    compare Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values.



    Settings

    The compare argument can have the following values:

    Constant Value Description
    vbUseCompareOption 1 Performs a comparison using the setting of the Option Compare statement.
    vbBinaryCompare 0 Performs a binary comparison.
    vbTextCompare 1 Performs a textual comparison.
    vbDatabaseCompare 2 Microsoft Access only. Performs a comparison based on information in your database.



    Return Values

    Replace returns the following values:

    If Replace returns
    expression is zero-length Zero-length string ("")
    expression is Null An error.
    find is zero-length Copy of expression.
    replace is zero-length Copy of expression with all occurences of find removed.
    start > Len(expression) Zero-length string.
    count is 0 Copy of expression.



    Remarks

    The return value of the Replace function is a string, with substitutions made, that begins at the position specified by start and and concludes at the end of the expression string. It is not a copy of the original string from start to finish.
