Its not working because you output $im_id=1 you should output var im_id = 1 instead.
The reason it's not working is that php replaces variables inside double quotes with the value of your variable. This makes for easy templating. For more information see the variable parsing section of the php docs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
