Print Report Command

Hello there,

I was implementing a "preview report" button to one of my forms that has a subform in it. To give you background, the form shows customer information, and the subform shows all invoices outstanding for a particular customer.

When I place the "preview report" button in the subform with where all the invoices are listed, its main goal is as the name says to preview the invoice that I have already setup (in report view). It prompts me with a "enter parameter" pop-up box with the line:

"Forms!FrmSalesInvoiceViewEditFINAL!invoice_id"

I have two questions:

1) How do I change "Forms!FrmSalesInvoiceViewEditFINAL!invoice_id" for it to say some other thing?

2) How do I have the pop-up box so that instead of prompting me to enter a parameter, that instead it "takes a value" from a textbook I designate and show up with the corresponding invoice.

For example:

when I click the "preview invoice" button, the corresponding invoice pops based on taking invoice number 2007001 (instead of asking me to input 2007001 as the parameter".

Thanks in advance!
