What choroba is showing is called the "flip flop" operator. Have a look at this Flipin good, or a total flop? in the tutorials section.

Other techniques could possibly be applicable, but I don't know enough about what you are doing to make a suggestion. As always, showing some actual code that you are having trouble with is the best way to get quality advice.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
