Text Entry + click hotspot to advance won't work

I'm doing a step-by-step simulation of a user entering text into a field, then clicking a hotspot to get to the next slide, but i get an INCORRECT when I try to click in the text entry to type. I want users to be able to type, then click the hotspot. Even if I have to separate this into two slides (one text entry, one hotspot click), how can I get the slide to advance when the user has completed the text entry? 

This is part of filling out a form, so I don't want to put a SUBMIT button in there.

File attached. The only thing I can get to work is to advance the slide if the user clicks anywhere outside the text entry box, but I'd prefer to make sure they click the proper spot by adding that hotspot. I'd also accept that the slide advances if they type the correct value into the text entry, but I don't see that option. Thanks.
