    these are not errors, only warnings

    They are not syntax errors, so that the program will compile and continue to execute, but they are likely to be logical errors. Don't dismiss warnings unless you know very well what you are doing. They are an immense help for you, take advantage of that.

    Sorry, but I down voted your last post, because I think this is the wrong reaction to the help being provided to you.

    You said:
    Hey, these are not errors, only warnings, but thanks ...
    They are indications that either your data is not what you claim it is or that there is a logic flaw (read 'bug') in the code. Both need to be considered and fixed. (See node 482733 for a particularly egregious example of this.)

    Clearly stating the question you want answered is the first step to true enlightenment. Always let "use strict" and "use warnings" be your guides on your journey.


    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
