What do you mean by that? Do you get a message box which misspells some Turkish text?

It fails because something is wrong. I give up, why?

Bad usage of IsNothing function[^]! IsNothing returns a boolean value indicating whether an expression has no object assigned to it.

Try this:

VB

Dim question As String

question = InputBox("Capital of Turkey?", "Question 2")
MsgBox "The answer is " & IIf(question = "Ankara", "", "not ") & "correct!"

Note: to be sure that one string is equal to another, you need to know that comparison depends on many factors, such as: site-code, big/small letters, etc.

I'd suggest to read this:
Comparison Operators in Visual Basic[^]
StrComp Function (Visual Basic)[^]
