That doesn't make any sense to the netlister. You use source= when you have 
made a symbol that represents an entire hierarcical subcircuit, with all its 
inputs and outputs. Then you associate source= attributes with the symbol so 
that the netlister can find the schematics associated with that subcircuit. You 
also have to tell the netlister where to find such schematics in gafrc.

The whole input/output symbol thing can be very confusing until you understand 
how the netlister works. If you're not using hierarchy, I recommend avoiding 
those symbols and just attaching netname= attributes to nets. All nets with the 
same name will be connected together. I sometimes use busses to visually 
indicate global connectivity.

If you want to use some sort of IO symbol to connect nets together on different 
sheets at the same level, use the net= attribute. Look at gnd-1.sym to see how 
that works.
