What exactly to you mean when you say:

perl doesnt allow me to use '==' to compare values in this case only.

What exactly did you ask perl to do and what exactly did it say in response.

What do you mean it in the phrase:

i am sure its integer

Do you mean "id" (as in the two chaacter string consisting of the letter 'i' and the letter 'd')? That's not an integer.

value stored in id is integer, but cant i use '==' thr, thats wat my question is...
