Android Question Incorrect message of unused variables

Hi
Why do I get a message that my variables ru, lu, tu and Bog1 are not used, when I am using them?

Why do I get a message that my variables ru, lu, tu and Bog1 are not used, when I am using them?
You better put your code in code tags before Erel sees this. You are lucky, I think Friday is a partial day off for him.
Also, when you have too much code, you are better off posting it in a demonstrative project. You can get a headache reading it the way it is posted now.

Please use code tags when posting code. It's the '</>' button at the left of the edit toolbar. Unformatted code is a pain to read and understand,

You are getting the not used message because you are setting their values but never actually using them, like assigning them somewhere. You are also unnecessarily declaring tu and lu twice. Your code could do with a bit of tidying up.

Hi, sorry I always mess things up. I did use those "</>" tags.

Graham, I am using indents in my code...not sure why it shows all code in a straight line down.
