NAND question

https://www.circuitlab.com/circuit/z5cjpn/test/

0V at Node2 would be 0V at both inputs of the NAND which should create a 5V at Node1. But I always get 0V.

What did I do wrong? Thanks.

Shorted the output of the gate to ground!

Delete the net (wire) connecting the NODE1 net label back to ground.

D'oh - yes, sure.

Ok - now I have a 1M resistor between the NAND output and GND and all is working. Thanks!
