You need to learn how to use the resources available - that will serve you much better than me holding your hand. All access functions and methods are described online. Now that is a clue there.
If your reports need parameters then you need to do docmd.openreport first where you can pass the parameter - look up the method. Then while the report is open, you can do docmd.outtputto, where it then will grab the open report with the parameters and output it.
Alternatively, you can rewrite the recordsource of the reports, so that that query incorporates the required parameter, and then you would not have to do the openreport first, because the report output via the docmd.outputto would have the right data. If all this makes no sense (yet) stick to the previous paragraph.
And all of these docmd statements can simply be written one after the other in a command button's On Click handler, so you can execute them by clicking that button. Google access command button.
