As I've said before, I'm a beginner at this. I just tried to actually use  
the 74_pwr.sym in an existing scheme, but I couldn't get it numbered  
automatically correctly. What am I missing?

First I manually set the âdevice=â to match existing components, then I  
added ânumslots=â to match. IN some cases it's 4 and in some cases 6 (NOT  
gates for example), but no matter what I did it was numbered wrong, with a  
higher number than the existing components.

What am I missing? Should I edit the symbol itself or should I set  
something in the schema or what?

It was all so easy before, when I had the ânet=â thing in the component  
symbols, but someone said that that's not the way to go, for some reason.  
At least it was very easyâ
