Simple question

I want to add the fpda boeing callouts that start at 500' and work down to the 10 foot mark. I think its a fpda_boeing_callout.gau How can I add this to my other jet panels, currently I have it on one of marco Spada's MD-80 Golding reworked panels.I thought all I had to do was add that gauge in the main guage area in the panel.cfg, but it does not seem to work.Thx!Hornit
