You should check the value of each_value at the point when the script
fails.  It sounds like split() is getting passed a string that doesn't
contain any '_' characters at all, resulting in a sequence with only
one value.  Passing 1 as the second argument ensures that there will
be at most 1 split, but there may still be fewer.
