Problem with if statement logic- Need help!

I'm trying to get my main menu working properly. I have three chapter selectors. When selected, each will active a different camera with the proper chapter backgrounds. Each chapter's camera's culling masks are set to only see the GUITexture for that specific chapter's levels. This works great. Back button brings me back to the main menu. it's all working how I want. problem is, no matter what method I use, i cannot get the GUITexture buttons to STOP WORKING. See>

In Main Menu- Main Menu Buttons(Yes)/Chapter1 Buttons(No)/Chapter2 Buttons (No)/Chapter3 Buttons(no)

In Chapter 1- Chapter1 (yes)/Main Menu Buttons(no)/Chapter2 (no)etc....

In Ch2- Ch 2(yes)/Main M(no)/CH1 (no)/etc...

That logic seems sound, right? But whether I use guiTexture.enabled=true/false; NO effect. Ok, just wrap the level select code in an if statement right? such as if(canClickCH1==true){ Allow clicking of chapter 1 levels }

DOESN'T WORK. No matter how I arrange my If statements. The code below is the code I use for Chapter 1 level select. (Same for chapter 2, but the variable names are changed) yet it's not working. At all. There's got the be something wrong with my logic somewhere. Can someone help me figure this out? It's been driving me crazy for days. thanks for your time. I just want to disable all the GUITexture buttons I'm not suing in the moment and only be able to click the ones I do want to use. (This is messy code with a lot blocked out. That's either for testing ir something I haven't deleted yet. Sorry.)
