Very simplified example of my problem:

in FLA:

```auto
#include "exfile.as"
var thenumber:Number = 52;

thenumber.helloWorld();

```

in exfile.as:

```auto
Number.prototype.helloWorld = function() {
  trace("haha!");
};

```

I know it gets included, tried traces. This gives me “no method with the name … etc” I know its very simplified, but where is the problem?
