Without code, we would have to guess. How about you give us a relevant code fragment?

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

If you think this is a real question, then you should not be writing any sort of code that anyone will ever use. As Griff said, there is NO way we can debug code we can't see, and if that's all you know, then you're obviously incapable of debugging/programming, too. I hope no-one is paying you to code. If you're doing a class, talk to the teacher. If you're teaching yourself, try harder and come back to us when you have a real question.

I'm going to guess that the placeholder has not been initialised at this stage. Set a breakpoint in your code and step over the point where you are attempting to add it. Inspect the variables to see whether any are null.

In future, this should be your first tactic when you get this exception. A quick debug session is a much better bet than waiting for others to solve them for you. Also, if you can't figure out what's wrong, please post the code so that we stand a chance - if you don't we don't have all the information.
