Adobe Designer/Adobe Reader Compatibility Question (with Data Connection)

I have used Adobe Designer 7.0 to build a simple form to be used by our employees for Accounting classification. Within this form I have several drop down list boxes, some text boxes and a button. I have two data connections, connected using the OLEDB wizard, to an access database I have on a shared network drive. I pulled some code from the net that uses both Javascript and FormCalc to manipulate the data on the screen. On my desktop, where I have the full Adobe suite, the form functions as expected. The drop down boxes populate and the button will refresh the text boxes based on the list box selection. On another user's machine, I set up the ODBC data source, and tried opening the PDF document. The form opens fine (the Reader is 7.0) and populates the drop down boxes with data from my Access tables. However, when I click on the refresh button (which uses the FormCalc script), I get a scripting error:

Error: accessor '$sourceSet.DataConnection2.#command.query.CommandType' is unknown.

The full formcalc code block is as follows:

----- form1.#subform[0].Button1::click - (FormCalc, client) ----------------------------------------

if (Len(Ltrim(Rtrim(SelectField.rawValue))) > 0) then
      $sourceSet.DataConnection2.#command.query.commandType = "text"
      $sourceSet.DataConnection2.#command.query.select.nodes.item(0).value = Concat("Select * from none_AP_VENDOR Where NAME_KEY = ", "'", Ltrim(Rtrim(SelectField.rawValue)) ,"'")
      $sourceSet.DataConnection2.open()

      $sourceSet.DataConnection3.#command.query.commandType = "text"
                $sourceSet.DataConnection3.#command.query.select.nodes.item(0).value = Concat("Select * from none_GL_TRIAL_ACCT Where NAME_OF_ACCOUNT = ", "'", Ltrim(Rtrim(AccountDesc.rawValue)) ,"'")

                $sourceSet.DataConnection3.open()
endif

Is this type of code supported by the Reader? Any help or guidance would be appreciated.
