App - Script

Hi,

is there any good source I should read to get this problem solved?

Man-pages .. Classic RTFM applies here.

im stuck in there few day and really want to be suggested a little plzzz =))

Look at the challenge name. It is a hint itself. Check the source code and find a way to make the code run a little differently.
I found it useful to copy the source code and test it on my local machine.
