Mismatched LayoutGroup.Repaint error!

[Seith]

Hello, I'm a new user of NGUI and I really like it!

Since I'm still a newbie at NGUI though I'm getting an error message that says "ArgumentException: GUILayout: Mismatched LayoutGroup.Repaint". And I can't figure out what I did wrong. Could anyone help me please?

Here's the full error message from the console:
