Mu's answer sounds reasonable. I am not sure if this is strictly necessary, but you might also try to put braces around searchStr .
I think your problem is actually on line 13, not 31, and I'll even tell why I think that. Not only does your script not have 31 lines but, from the fine manual.
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.
