In the future please don’t just put screen of error. Ask question, problem and put your code in code tags Using code tags properly
Remember - be precise, concise, informative

Short tutorial how to deal with errors:
1. Read error.
2. Read error second time.
3. Read error third time.
4. Read error and answer “which line occurs it?”.

10. Ok, now you should know what the error is about, so read it again and fix the problem.
11. Ah, you don’t know how? Read your code step by step, line by line, letter by letter, to make sure you understand it in 100% and you know what does each line do (debugging is great!).
12. Find your mistake, fix it.
