PHP If statement in input tag value, and form not processing

My form isn't processing. Once I've entered details or even if not, I'm getting the else statement echo "Your password reset key is invalid" on line 95. The key is correct but...

I think there's an issue with the if statement on lines 160-164 for the value of the input tag. I think it needs wrapping in a php tag, but am not sure what's wrong...?

Hope someone can help. Thanks.
