User types in wrong number
I have screen captured a walk through of a software for users and at one point they need to enter the correct number to move to the next slide. Everything is there for them, the narrator, the balloon the menu wording for them to get it right and if they do, they are take to the next slide. BUT, just before I went to publish it, I noticed that if I typed in the wrong numbers I can't change them and even if I go back to the previous slide and then come back to this slide, they wrong numbers are still there. Is this a variable thing and if so how do I learn what to do.
(When the users types in the wrong number a notification comes up saying it is incorrect and try again. If I try again it won't let me erase the wrong numbers)
