Welcome to the forums, tomtom!

First off, make sure the guages are in your gauges file by checking them visually.  If I remember correctly, they should be in their own file labled RCB Gauges or something similar.  If they are all there, check to make sure the names in the panel.cfg file you are editing match those of the gauges in the RCB file.  If this is all straight, make sure the numbers of the gauges in the panel.cfg are numerical, and that they don't repeat.  That's all I can think of . . .
