postgresql syntax error at or near create when creating a function

There are two errors in this code:

Variable declarations use Locations%ROWTYPE (location*s* - with "s" at the end),
while SELECT * FROM Location INTO statements reference Location table (without "s").

return planetDist-DriverDist; references Plan**e**tDist
while declaration says plantDist integer; (without "e")

After fixing these two errors the function compiles and works fine,
see this demo: http://www.sqlfiddle.com/#!1/38d68/1
