How to change a large complex Report query in code

The dates in this query begin as #1/1/2013# And #12/31/2013# and I need to change them with the dates in the text below.

Dim XbyAfrom as Date
Dim XbyAto as Date
Dim qdf As QueryDef

                XbyAfrom = #3/1/2013#
                XbyAto = #8/31/2013#


Set qdf = CurrentDb.QueryDefs("qy_DateToDateTransactionReport")
qdf.Parameters!TradeDate = "Between " & XbyAfrom & " And " & XbyAto
Reports![RpQtr-Transactions131231YTD by account].RecordSource = "qy_DateToDateTransactionReport"
                DoCmd.OpenReport "RpQtr-Transactions131231YTD by account", acViewPreview, "qy_DateToDateTransactionReport", "HHID = " & ClientNowPrinting

This compiles and runs ok, but doesn't work to change the date range.  Am I even close?

Some duplication here, but you get the idea.   What's wrong, please?

All I need to do is replace the dates in a huge query.  Not so simple using all this text in code, because of all the line breaks.  I'm considering just "finding" the dates by using Right and Left instructions and replacing them by manipulating the string.

Where are your dates coming from?  If they are in a form you can use [Forms]![FormName]![FormField] as the query parameter.

Yes, they are coming from a form, so...

qdf.Parameters!TradeDate = "Between " & [Forms]![FormName]![txtbox1] & " And " & [Forms]![FormName]![txtbox2] should work?

Why don't the variables work just as well?   They were assigned the values from the same form controls.
Probably Not.  TradeDate as a parameter in the actual query probably makes the query look like "...WHERE SomeDate = [TradeDate]"  If that is true you need to change the query to say something like "...WHERE SomeDate BETWEEN [Forms]![FormName]![txtbox1] AND [Forms]![FormName]![txtbox2]  Then you need to do NOTHING in the vba code.
That's simple enough, and viable, but I had intended the Report to be used with or without the Form, so can I just replace the variables in my original code with the Form references when the Form is open?
I tried replacing the variables with Form control references, and it does not appear to work.  No errors thrown, but no effect on the Report date range.

qdf.Parameters!TradeDate = "Between " & Forms!fm_ReportPrinter!txtYtoYbyAcctFrom & " And " & Forms!fm_ReportPrinter!txtYtoYbyAcctTo

Does this need some kind of refresh or update command to take effect?
How can I print the parameter after the command is executed?

Debug.print qdf.Parameters!TradeDate    ??

What does your actual query look like.  You can't set the parameter "TradeDate" = "Between Date1 and Date2" because that is not a parameter.  The parameter needs to be a single date.  The "Between" needs to be in the original query.
I like that.   Plenty of meat to digest.  Thanks a bunch!
So the Date1 and Date2 need to be separate variables?
Yes, Date1 and Date2 need to be separate.
Thanks again.   I have my homework assignment for tomorrow.
