Test Mode screencast results slide

Hi.

I'm trying out a Test Mode screen cast for the first time in Storyline 3 with just three slides. After I have performed the required action for the final slide, before I have the chance to click the submit button in the Player to confirm my action, the results slide appears automatically.  Ideally, I'd like the results slide to appear only after the submit button is selected or at least have a time delay to allow time for the user to select the submit button (which does work if you select it quickly enough). The only trigger on slide 3 is a Player Trigger to submit the hotspot interaction when the user clicks the submit button.

Any ideas much appreciated! :)

Thanks, Tina
