The word “it” is missing, but the word “If” should not be there. That’s my guess.

That was my thought in post #2.

Only the author can answer for sure.

Which is what he did in post #3.

Well, then I’m at a loss. It’s up to the author to clear this up because keeping “if” and adding “it” makes no sense.
