Well, I decided to give this custom-gauge hobby a try. I purchased FS Panel Studio so that I can be able to create and modify my own set of car gauges. So far so good, the gauges LOOK nice and ready, but it's the GETTING-THEM-WORK part that is getting on my nerves.

I have created a pair of gauges for the Ferrari. One is the Tachometer [left side] and the other is the Speedometer [right side].

When I tested them out in FS, they appear correctly. But they just don't work.

Are there any detailed tutorials on how to handle XMLs or is there anybody who can help me fix these?

I don't know XML. And when it comes to it, I don't know where to start.

Here are gauges as they appear in FS Panel Studio:


Any suggestions? Advice? Help?
