V2 0 volts problem

[virgodave61]

I measured V2 and found it to be 10-22 mv. I checked R1 and the switches as well as all resistors from the input to the test point and re-soldered them. When I set it to make a 5 volt signal it displays as about 5.6 volts. I measured it with another scope and it says its 5 volts. I dont really mind if its off a little, but would like to fix it.
Thanks

The error may be caused by the errors in resistors R5 - R11 which set the gain of the amplifier.
