With reference to your next-to-last sentence, look at the dictionary and discern the difference between “its” and “it’s.” You will find that “it’s” is the contraction of “it” and “is.” What you should use is the possessive pronoun, “its.”
A very, very common error.
Spell checker won't catch those, but I usually do myself, on the third or fourth review.
