It has to do with the order of execution inside an structure.First, any of the element.Then, any Then and last, with all its carry: ,, etcThen the rotating/shifting elements.This is for FS9, I'm not sure it is interpreted the same way in FSX.Tom

Hi,I tried this one, but no succes (backlighting)@power(L:Autobrake,number) s0Jan"Beatus ille qui procul negotiis..."

Jan, It seems that you have a rotary switch for autobrakes.Ok, then supposing the switch indicator points to north (0) position, you could try this: goes ie from 0 (OFF) to 4 (RTO); each position rotates 30 degrees, north (0) is position 2Then,..etcThat's it. In case it doesn't work with our example, you can try placing one section into each ... section.Tom

Tom,I use this one without any problem, only some more code:(L:Autobrake,number) s0(L:capt instr bus AC volts,number) 100 > (L:panellights, bool) andl0Jan"Beatus ille qui procul negotiis..."
