Is there a script that makes a field where the visitor can write something and then the thing the visitor wrote is compared to another text and then the diffrence is printed on the page?
am I in the wrong forum..?

You may be in the wrong forum: this is the kind of thing that can be done with JavaScript (clinet side)... or with a server-side scripting language such as PHP.
