electrical problem adcin

[skimask]

code is very simple and i am getting reading from pic so hookup is ok
think the problem is the resistance is so great might need a amp but hate to go through this two wire resistance is connected to ground and pin of pic does flucatate on voltmeter as expected again readings are in millivolts
just dont seem to get pic to respond dont know what range of resistance
or voltage

hook up is straight foward 2 wire device one wire to ground (vss ) other to pic using adcin command

If the code is very simple, then post it.
If the schematic is equally as simple, then post it.
Maybe then, you'll learn something, and then you won't have to ask so many questions later.
