This may help you (or not). We have an excel file that has a hyperlink that opens the IE Plugin, opens a particular document and opens to a specific sheet based on a variable. Heres how we implemented it.
1) In the QV document we created a variable vOpeningSheet
2) In the Document Event Trigger we call a Macro to run OnOpen. The Code is
set v = ActiveDocument.Variables ("vOpeningSheet")
This opens the plugin, opens YourDocument.qvw and send a value to the variable vOpeningSheet. The OnOpen is then triggered with the variable to open the document to the sheet set up in the Macro above.
