W32 IO Expansion Board

I have a quick question on the W32 IO Board's analog input.  Right now, all 8 inputs with nothing connected show around 700-800 for their values on the analog input value on the webpage.  With nothing connected, the 10-turn pots do not impact the values.  Connecting A-GND or A-5V to an analog input also has no impact.  Is there something I need to do to get these inputs to work?  Do I need to add resistors or something?
 
Did you short the ground jumper on the analog ground to board ground?  By default, both digital and analog ground are floating, so that users can connect them anyway they like. If you do not have separate ground, please use a drop of solder to close the SP1 and SP2
