"start-point" is not a valid identifier as the "-" isn't permitted
in a variable name.  This is the case for just about every language
out there.  HTML/XML & CSS are the only languages that come to my
mind in which the dash is considered a valid part of an identifier.

You either mean something like "start_point" (with an underscore
instead of a minus), or you're performing a subtraction of "start
minus point", in which case you'd have to assign those values before
you use them.
