IN order to help you, please provide additional information.
Is this a first time new installation?
Did you have a picture of the old thermostat and the wires?
Can you upload a picture of the nest back plate with the wires installed?
Did you have a C wire installed in your old thermostat?

I appreciate the help, Ken.
Please let me know if that helps or if the issue still persists.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
