That vi is an old 2014 version of the now NT Write Value.
These are the vis that send data to the dashboard and they were updated in 2015.
The reason you can't find it is because it is not in the pallets anymore in 2015.
The new templated teleop looks like this now
The new "NT Write Value.vi" is found in the dashboard pallet
I would right click on the old vi and replace it with the new "NT Write Value.vi" found the the dashboard pallet
The wires still may be broken after the replace.
Delete the broken wire
Click on the selection menu below the vi and select "NT Write Numeric Array"
Wire the ouput of the Drive vi to the input of the NT vi
Hope this helps
