fill-in-the-blank, message box (case 5459)

[litterachi]

hello~everyone,

I have a problem about fill-in-the blank's message box.

I want to design experiment. Let participant to read a number serial(ex.12345), then ask participant to recall and enter the number serial in the next page.

I used several fill-in-the-blank (m*****,r12345) in the recall page.
The problem is : When I enter the wrong answer, it will show message box that include the correct answer.

How can I delete the correct answer in the message box?
