Why does this coding give me an error  when I try to set QT to the connectstring?  What can I do to make it work?
Sub MyQuery()
    Dim WSD As Worksheet
    Dim WSW As Worksheet
    Dim QT As QueryTable
    Dim FinalRow As Long
    Dim i As Integer
    Dim ConnectString As Variant
    Dim FinalResultRow As Long
    Dim RowCount As Long
    Dim stock As String
   
        Set WSW = Worksheets("Portfolio")
    Set WSD = Worksheets("Workspace")
   
    'Clear workspace
    ' On the Workspace worksheet, clear all existing query tables
   
    'TRAP ERROR IF QUERYTABLE DOESN'T EXIST (Make a subroutine to clear and call it here!!)
    On Error Resume Next
        WSD.Range("A10:G80").Select
        Selection.QueryTable.Delete
        Selection.ClearContents
   
    stock = "MO"
    'Build the ConnectString
    'stock = WSW.Range("A3")
   
    ConnectString = "WSD.QueryTables.Add(Connection:=" _
    & """URL;http://finance.yahoo.com/q/hp?s=" & stock & "+Historical+Prices""" _
    & ", Destination:=WSD.Range(""$A$10""))"
   
    Set QT = ConnectString
    'MsgBox ConnectString
 
    ' On the Workspace worksheet, clear all existing query tables
   
    'TRAP ERROR IF QUERYTABLE DOESN'T EXIST
        WSD.Range("A10:G80").Select
        Selection.QueryTable.Delete
        Selection.ClearContents
   
   ' (THE FOLLOWING TEST STRING WORKS)
   ' Set QT = WSD.QueryTables.Add(Connection:= _
   '     "URL;http://finance.yahoo.com/q/hp?s=MO+Historical+Prices", Destination:= _
  '      WSD.Range("$A$10"))
         
    With QT

You're trying to set QT to a string type but you have it defined as a Query table.

I corrected the error with assigning the value to QT...If you're getting errors from there, then it's probably best we backtrack and figure out what it is you're trying to do...Probably going about it the wrong way.
Explain the best you can what it is you're needing.

Did not see you suggestion:
 Set QT.commandtext = ConnectString

Debug takes me to the connection string:
ConnectString = "WSD.QueryTables.Add(Connection:=" _
    & """URL;http://finance.yahoo.com/q/hp?s=" & stock & "+Historical+Prices""" _
    & ", Destination:=WSD.Range(""$A$10""))"

The roll over message tells me:  ConnectString=Nothing

Have you tried recording a macro of importing the website and then editing the recorded connection with the variables?
Seems like it would be much easier than you or I debugging the code.

Sorry, I seem to jumping the gun on you.
Following is what I am trying to do.
I have a stock symbol on a worksheet "portfolio.
I want to select the stock symbol and retrieve the historical data on the worksheet "Workspace"
The historical data is used in a calculation and is then deleted.
A new stock symbol is then selected and new historical data is loaded into the worksheet "workspace"

For some reason I am having trouble getting the stock symbol inserted into the query.

Yes, I have recorded a macro, but this gives me the stock symbol hard coded into the subroutine.

record a macro of you querying the website using one of the symbols.....afterword......use the recorded code to insert the stock vairbale into the query........much easier this way......
Just add your vaible declaraions, input box and what not, or you variable sets and replace the stock symbol in the query with:
" & stock & "
The recording will give you the query table syntax......

record it using one of your symbols and then post the code here....I'll edit in the symbol variable and other stuff using what you have above....

This is the recorded macro:
Sub Macro1()
'
' Macro1 Macro
'

'
    With ActiveSheet.QueryTables.Add(Connection:= _
        "URL;http://finance.yahoo.com/q/hp?s=MO+Historical+Prices", Destination:= _
        Range("$A$10"))
        .Name = "hp?s=MO+Historical+Prices_1"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .BackgroundQuery = True
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .WebSelectionType = xlSpecifiedTables
        .WebFormatting = xlWebFormattingNone
        .WebTables = """yfncsubtit"",16"
        .WebPreFormattedTextToColumns = True
        .WebConsecutiveDelimitersAsOne = True
        .WebSingleBlockTextImport = False
        .WebDisableDateRecognition = False
        .WebDisableRedirections = False
        .Refresh BackgroundQuery:=False
    End With
End Sub

I need to have the subroutine read and paste the stock symbol into the code.  The use of an input box will not serve our needs.

It was a good tip you gave me.  I recorded the macro and inserted  " & stock & "  into the connection string and it worked.  
I cannot thank you enough
