The biggest mistake made by beginners, and you are manifestly a beginner
here, whatever else you may have done before, is to change too much
between tests.

If, between two tests, you only change one line of code (keeping the old
line as comment), then, when it no longer does what you expect, the
fault must have something to do with the difference between the two
lines.

Another general trick, in a language where undeclared variables are
permissible, is to write "banana" just after the new part (assuming that
you are not programming vegetably).  You know then that you should be
getting an error message (unless you have written an infinite loop);
and, if it is banana, at least your code above had a measure of
acceptability.  That also serves to prevent subsequent code interfering
with any visible evidence that there may be.
