    Question 'Enter Parameter Value' prompt showing the parameter value

    Hi Folks,

    A bit confused here.. I have an MS Access Form in which a value is entered into a Text Box, and then that value is supposed to be used as a parameter in a query (upon clicking a button next to said Text Box).
    Currently, when I enter a value into the Text Box and then click the button to run the query, I receive the 'Enter Parameter Value' prompt with the current value of that Text Box as the field that it's evidently looking for. The specific value that I type into the Text Box is what shows on that dialog box. If I re-enter that value into the actual prompt and click "OK", the query then runs with expected result. So essentially, it works - but I have to enter the parameter value into the Text Box on the form, and then re-enter that same value into the 'Enter Parameter Value' prompt. The latter is what I'm confused about.
    I'm sure I'm missing something obvious! Below is the code used on the form (within the 'OnClick' event of the button). Thanks!

    Dim db As DAO.DatabaseDim rs As DAO.Recordset
    Dim qdf As DAO.QueryDef
    Dim strUserID As String
    Dim strSQL As String
    strUserID = Me!txtUID
    strSQL = "SELECT tblImport_Final.UserID, tblImport_Final.Title, tblImport_Final.Location " & _
            " FROM tblImport_Final " & _
            " WHERE tblImport_Final.UserID = " & [Forms]![frmUser_Report]![txtUID]
        DoCmd.DeleteObject acQuery, "tempQry"
        Set db = CurrentDb
        Set qdf = db.CreateQueryDef("tempQry", strSQL)
        DoCmd.OpenQuery ("tempQry")

    Unresolved parameters cause more than one type of behaviour, including errors. There are several ways to deal with it, some much more complex than what I've found often works, and that is to assign the parameter value to a variable and use the variable rather than a reference. So assuming ID is a long:
    Dim lngID As Long
    lngID = [Forms]![frmUser_Report]![txtUID] 'or is it just Me.txtUID?
    strSQL = "SELECT tblImport_Final.UserID, tblImport_Final.Title, tblImport_Final.Location " & _
       " FROM tblImport_Final WHERE tblImport_Final.UserID = " & lngID
    I fail to see the point of repeatedly deleting and recreating a query def (most say it promotes bloat and corruption, so I joined that club) when you can simply run sql in code - which is where you are already. You can also create a qdef solely in memory by not giving it a name (use zls ("") instead).

    There must also be more code? I don't see where you use recordset, nor do you need to open a select query for use with a recordset.

    - "doesn't work" is no help. Post err msgs and where.
    - Use code tags for code/sql. Implement changes in copies of your database.
    Sometimes I talk to myself - like when I need expert advice.

    I avoid repeatedly deleting and recreating table or query objects. I use 'temp' table - table is permanent but data is temporary.

    Why do you find it necessary to delete/recreate query?
    How to attach file: To provide db: copy, remove confidential data, run compact & repair, zip w/Windows Compression.
