The error message says:

SYNTAX ERROR IN USER INPUT n f7-d6 on turn 9:

compose_move: #to is not a valid coordinate

When a variable has not been assigned a value, it is sometimes treated as a string literal of the named variable. So, what we have here is the variable named to without any value assigned to it. See where #to appears in the code, and make sure it has been assigned a value, and that that value is a valid coordinate.
