Hello!
I'm currently creating a form in PowerApps but I'm having a couple issues with hiding and showing fields based on specific answers. I have looked multiple videos and read multiple posts about this topic but for some reason keep getting some error messages.

These are the formula I've been using on the field I want to appear and disappear.


This is the card of the field that I want the formula to see and appear if the answer is "Si".

These are the error messages I'm getting on both formulas

Any help will be appreciated.
Thanks!
