Hi,

Your problem is that you are wiring an object wire to a chart object.

You are probably going to want to read through OOP a litte bit more, this simply wont work.

If you want to read the string from your sin.vi you need to access the string control from that object, by using your read string.vi from number flow class and then output to a string indicator.  Take a look at the image attached.

Hope that made sense

If your post title means you practice for a CLD exam, I tell you that an Actor Framework is just an overkill! Keep it simple! Almost all CLD exam scenarios can be done with a single loop state machine, and proper documentation. So if your interest is practicing for exam, I bring to your attention this specific forum board:

At this forum board you can get dedicated help, and reading other's posts you can learn a lot before taking the exam...

Good luck!

I would try to just attach a .zip of your project again. I'm not sure if it is that files were missing from what you attached but I couldn't find any place that you were launching any of your actors or where you were sending your actors messages.

To be honest im not sure that you fully understand how the actor framework works and what its used for. You enqueue a message class, just to dequeue it and destory the queue, unnecessary.   Then you use the write value vi and send that object as a message.  I just really feel you dont quite understand AF yet. If you havent yet, i suggest going through some of the tutorials.  Ive attached a link to a simple one.
