Ok I spoke too soon, I have successfully installed the Gauge in CS737-200 but have the same problem in CS737-200Adv, I have the V and the T on the simicon but no CS simicons. I have noticed one thing which may be relevant, in the CS737-200Adv panel.cfg.[Cockpit01] the bottom line is "gauge18=Captain_Sim.x737.sys2!main,1,1,1,1" this means that the amendment to that field has to be gauge 19 and gauge 20, this (gauge18=Captain etc.) does not figure in the CS737-200 panel.cfg. Could this be the problem?
