Fuel Quantity Needle

Hello, All, I was wondering if someone called help me. I'm trying to make a 3D Fuel quantity needle in XML for these fuel tanks:(A:FUEL TANK CENTER CAPACITY, gallon)(A:FUEL TANK LEFT MAIN CAPACITY, gallon)(A:FUEL TANK RIGHT MAIN CAPACITY, gallon)(A:FUEL TANK LEFT AUX CAPACITY, gallon)(A:FUEL TANK RIGHT AUX CAPACITY, gallon)and display them as Internal fuel with a needle:(L:Internal Fuel, gallon) 8.178 * dgrd /-/but I can't seem to get them to work.I've tried putting pluses behind them all, and one behind the last entry, but I think the whole formatting of the code is throwing me off.Can anyone help me?Thanks :)Jamal
