I'm very new to Qlik Sense and doing my very first button for Qlik report (table chart). Button should select "errors", or in another words, find out if there's the same vaccination date (Time column in my report) for the same person (Owner column shown as "Own..." in attachment picture from my report) and select them showing all the information of those owners highlighting the duplicate dates.

Unfortunately I don't have any idea what actions I should use for the button (I have been considering "select values in the field" and "select values matching search criteria, but haven't figured out the right expressions). Is the either one of those two the right choice or should I use different button action? What about the expression for the value. I have been considering if function. I know you can give many actions for the button. I presume I must make more than one action. Or is it possible to do my task with only one action?
