When calling a function, you can also pass parameters. These are simply numbers or strings that are made available to the function.
For simple questions about what the different features do you should just look it up in the manual.
It's also a bit difficult to imagine exactly what happens with that screenshot since we know nothing about the position of the objects or what they are there for. It's easier if you share your file, so we don't have to spend ages interpreting your event sheet and just guessing what it looks like in your layout.
If you don't want to share your file for some reason, you can recreate the bit you need help with in a smaller project.
Anyway, I'd love to help, but I'm not really sure what the problem is, and what your events are meant to do, and I'd rather not spend the next 30min trying to figure it out when I could just press the preview button and see it in a few seconds. <img src="smileys/smiley2.gif" border="0" align="middle">
