Just finished a VFE Standout
LPF is not working at all in any configuration.
HPF seems to be working properly.
When the toggle switch is put into the 12dB setting the HPF stops working as well...so in that toggle position neither filters are working.
Did my best to check for errors in the build.
Any help anyone is will to offer would be greatly appreciated.

Thank You
Call off the dogs...fixed the problem.
Thanks to anyone that took a look.
what was the problem with your build that you found and fixed?
In the LPF signal path I had 200k ohm resistors in the place of 220 ohm resistors. The resistors that set the bandwidth of the filter.
