The method is connected to the textfield. So that should be in order.
The simplest way to debug is to just print out what is happening
and check your debug/run console for output. Put this in your
methods and see what happens when you press enter/return in your
textfield:
NSLog( @"theWebView = %@, sender = %@, stringValue = %@",
theWebView, sender, [sender stringValue] ) ;
That line of code return this:
The Debugger has exited with status 0.

0x1249a0>, sender = <NSTextField: 0x1290a0>, stringValue = 24
It seems that it just returns the value I enter in the textfield. My
test.html file is bundled in my Resource folder so I don't get why
the action wont work with it. Maybe it's not possible this way.
The next step is to check if your javascript function is called (maybe
your page has some syntax errors and the function is not even defined).
Try doing something obvious in your javascript function, such as
changing text color to red, or something. If that works, then you
should use some other approach for scrolling, e.g. use scrollTo() or
some of its derivatives. But that is general JavaScript and not Cocoa
problem any more...
