Hi
I think from what you are saying you want to look at a macro . Go to Tools>Macro>Record new macro and either name it when prompted or settle for Macro 1(the default), now perform your actions i.e unhide your rows. Then click stop recording. You will now have a macro which you can attach to a Form button which will unhide your rows when clicked . You can do the same thing to produce a macro to rehide these rows
