  1. 2 Rg pin to MID and 3 Rg pin to END
  2. A Different schematic not in the image
That seems to indicate you are trying to connect a pot to the
RG pins to have adjustable gain ?

There are two "standard" ways to make an instrumentation amplifier out of operational amplifiers. One uses two opamps, and one uses three. You want the three-opamp version.

Search for 'instrumentation amplifier circuit' to get lotsa sample schematics.
