    Dim rs As New ADODB.Recordset
    Dim sql As String
    Dim display As String



    Private Sub Command1_Click()

    display = Text1.Text & Space(1) & Text2.Text & Space(1) & Text3.Text

    '‘define SQL query
    sql = "Select * from [" & display & "]"
    '‘specify format of SQL result and assisgn to ADODC
    adogrid.CommandType = adCmdText
    adogrid.RecordSource = sql
    adogrid.Refresh
    '‘Display result in the datagrid object

    You show two different sql statements the one in the window is not valid then one in code looks to be ok assuming that display is a string variable that holds the name of a table. If it is an empty var then that too would be invalid

    Bad Idea.

    Database != WorkBook.
    Table != Spreadsheet.

    • If the user enters a name that isn't a valid table name for your database, your application dies.
    • If the user enters something "nasty", your application dies.
      Obligatory XKCD Reference: Little Bobby Tables
    • Having created a table, you then need some way of knowing what that table was called. That's generally done by having another table that holds all the table names! It rapidly gets very complicated, making more work for you.


    Unless you have a very, very good reason to do so, you should be using a single table for this and the values entered are just fields within that table, for example:

    Code:
    select * from users ; 
    
    +----+------------+------------+-------------+ 
    | id | Last_Name  | First_Name | Middle_Name | 
    +----+------------+------------+-------------+ 
    |  1 | Flintstone | Frederick  | Joseph      | 
    |  2 | Flintstone | Wilma      |             | 
    +----+------------+------------+-------------+
