I am in the process of writing a GUI and keep running into an error that I can't seem to get rid of. I still have to add various listeners to make it work, but right now I'm simply trying to make the GUI show up and look the way I want it to.
I've tried isolating the problem to figure out what exactly is "illegal" about my components...but to no avail. It's entirely possible that I am overlooking some simple error, I've been reading code all day so perhaps my eyes just need a break .
If anyone is able to figure out the problem, I would appreciate it.
There are 5 or 6 lines that cause the same complaint, usually the first component placed in each container. If you remove the second argument in the call to add() for each of them, the complaints go away, and your GUI will display. Why the complaint? I'm not sure. I don't have much experience with GridLayout. More research (or a response from someone smarter) should provide a reason.

The add(...) method is used to add components to a Container. Normally the component is added as the last component of the container. The add(...) method also allows you to specify the "position" of the component in the container. That is, first, second, third etc. To add a component at the start (first) you would use:
JLabel.LEFT is not a "position" it is an "alignment" so it is an ivalid value.

Thanks for the help guys, I managed to get it. After removing the "JLabel.LEFT" and switching a few things around, as per your suggestions, I was able to get it to show correctly.
