Your problem is in the lines above, check carefully where are you
storing the values and what are you using for your regression. Also,
your question is a borderliner, do not expect the community to worry
about your problems if you do not put an effort to write your mails
and make your debuging code readable and short (yeah, succinct)

X is different that x
