[kicad-users] A rule check issue that is confusing me. I have GND comming from a header

A rule check issue that is confusing me. I have GND comming from a header. 
Their is the same GND in other places on the circuit.
But I get a error like it should be driven. But that sounds like a short...
ERC: Warning Pin Power_In not driven.
I have GND hooked to a header... Now that same ground simbol is in the rest of 
my circuit. 
Please help.
