Why isn't my if statement being executed?

I am currently creating a security system, and I have it to where it pulls text off of multiple files on my computer, and puts that text into a URL which grabs more text. But when I do an 'If Statement' asking the system weather the text equals true, and or false. it does not work. It does not even give me an error to work off of. Any ideas?
