Answer: 
Are you sure that the punktzahl-variable you are adding together is the one from class antworten? You're writing antworten.geo, but not antworten.punktzahl. 

If you try to look up the variable in the IDE where do you arrive?
I think that @thoredge is on the right track. Try replacing this line:

```
antworten.punk_str = String.valueOf(antworten.punktzahl);

```

With this:

```
antworten.punk_str = antworten.punktzahl.getClass().getName();

```

If `punktzahl` is really a `long`, you should get a syntax error. Otherwise, you will see what class Java and Android think it really is.

There are two ways I can think of that it could end up being some other type. The first, as @thoredge suggests, is that you aren't actually getting class `antworten`. Is it possible that you have two different classes with the same name in different packages in your project?

Maybe `com.zombies.survive.antworten` and `com.zombies.antworten`?

Is it possible that you're looking at an old copy of `antworten`? Maybe it didn't get recompiled, and an earlier version actually used a `String`. Try doing a make-clean/build-all (Project > Clean in Eclipse). Try restarting your IDE. Try deleting the source, or even the project, and checking it out of source control from scratch.

The last thing I can think of is that it could be a Classpath issue. Is there any possibility that you have a jar file in the project with a class named "antworten" that you could be getting instead of the one you are expecting? I have seen some very weird things happen in the past, for instance, when two apps were installed on WebSphere and they used different versions of the same library. There were two different versions of the same class on the classpath. The result was **totally** mystifying. I had a very unpleasant afternoon helping a co-worker figure it out. So make sure that isn't happening to you.
