Welcome to the forums Jay
I understand what you're trying to say about outputs affecting inputs - as one forum member's signature has it "an output is a PLC's way of getting it's inputs to change"
As the others have said, if you post what you've done so far, and some "this bit is working, but it gets to here and doesn't do this, I can't work out what's stopping this bit from turning on..." comments then a lot of folks on here will jump in to help you out. We're a friendly bunch generally but we like to know that you're at least making a concerted effort before we volunteer our time to help out
