This means exactly what it says: you are using a variable named "hhe"
somewhere in your code, but you have not declared it. The error message
should also tell you on what line this variable is first used.
Removing the "implicit none" statement will cause the compiler to
automatically treat the "hhe" variable as if it has been declared REAL.
This will of course cause the error message to go away. This is not
usually a good thing -- your bug is at least as likely to be that you've
accidentally types "hhe" where it should be "he", or something of that
sort. Or else you've forgotten to declare the type of "hhe" before
using it, and you should fix that.
