I am trying to pass a value from a command button on a form to a report. I have a form that has 4 command buttons. Each button opens the same report only with different filters. I need to figure out how to also pass a value from the command button to change the Report Title so that the title isn't the same each time.

There are probably a good many ways to achieve that.
I would put an invisible textbox on my form, fill it with text (the wanted title) from the command buttons OnClick events, and read that value from the opened report.

Hope this helps
