Navigation Bar / Subform Problem (1 Viewer)

Hello,

For the life of me I cant seem to figure out the correct syntax and was hoping someone could provide some help and the specific syntax needed.

I had a form "Quotes" that worked perfectly and upon clicking a button opens a report using the following code and set the Quote_ID to the Quote_ID of that specific record:

DoCmd.OpenReport "rptquoteExtreme", acViewPreview, , "Quote_ID=" & Me!Quote_ID

I have recently added a navigation bar called "Navigation" and now get the message "Enter Parameter Value Forms!Quotes!Quote_ID" when the button is pressed.

I understand my form Quotes is now a subform but cant seem to get right syntax to identify the value of Quote_ID within the form Quotes so the navigation bar works correctly.

If you could provide the specific syntax that would be great.
Thanks
