Input text field hit test

Hey guys,

I have a input text field with a “?” mark in it to prompt you to type in answer.
The problem is I want to be able to clear out “?” mark when the user start typing in their answer.

Ideas? Im not to good at this stuff…

People are not deleting the “?” mark and typing in their answer so its “incorrect”.

Any ideas on how to do this?

Thanks!
