Continuous subform with checkboxes

Hello Experts,
This problem is driving me nuts and I would appreciate any help you can provide.  I created a form for my application that consists of a main form and 2 continuous subforms, each of which contains a subform control on the main form.  Everything works perfectly, except for the ticking of checkboxes on the second continuous subform, which will be discussed in detail below.  

The purpose of the form is to enable the user to do “bulk” changes to any of several report classifications defined in the Chart of Accounts. The form works like this: The user selects via combo boxes on the main form, a report that has the accounts with the line item classification that they want to change.  The first continuous subform returns a list of all the accounts and amounts from the report that has the line item selected.  The second continuous form repeats the list of accounts, but has checkboxes for the user to designate which accounts are to have their classification changed, and has a combo box with a selection list for the new classification.

Everything works fine until I try to tick or untick a checkbox.  I get an error message “Error 3061…..Too few parameters…2 expected. ……….on the line :

    Set qD = dBs.CreateQueryDef("TempQry2")

 This does not make sense because the querydef generates the query perfectly.
In fact, if I go to the query window and open the query (“TempQry2”), it shows that one checkbox has been ticked.  Help!!!

Here is my code:
