Change post submit text

Hello! I have a webpage that contains an easter egg. On the webpage is a riddle in secret code that the user is trying to figure out. I have a form block used currently where they enter their email and the code to try to solve the riddle. is it possible to give them different post-submit text based on if they enter the correct secret code? (Ex. You are successful vs You are wrong, try again)

Unfortunately, the Squarespace form doesn't have the option for actively checking the form fields and adjusting the output when submitted. You'll want to have a look online for some answer-checking code that could do this.
