Variables needed for specifying text in data-entry field?

Hello!

I don't know what I'm missing, or how, and would love any and all feedback/help. I'm creating a self-paced navigation Scene in Storyline 360 where the learner has to write in the correct text in data-entry fields in order to proceed. For example, on one slide they're logging in and need to write in a specific username, so the in the data-entry field they need to write "Username1" (example). Once they click Enter, they can then proceed to the next slide, but if something is misspelled/mis-written, they will not be able to proceed.

 

I've tried to create these slides both as a freeform interaction, and without, and can't seem to get everything set to what I need. Any help appreciated, thank you!
