What value does it read?  This sounds like insufficient acquisition time.
When scanning multiple analog inputs, I usually use an interrupt to get each
A/D reading.  The best thing is to switch to acquiring the new channel
immediately after grabbing the data for the previous one.  That way the A/D
has most of the time between readings for acquiring the channel and settling
the value.  You still have to make sure of course that the total time is
long enough at least for the minimum acquisition and the minimum conversion.
Both you're inputs are slow, so this should be no problem.

How often are you doing an A/D conversion?  How is this being triggered?
What causes your code to grab the result of a conversion?
