i tried this bt cant work

yes, it cannot work, too much stuff in blender order (random)

you're trying too many things at once in a blender

package statements do not go into if blocks

putting code in between subroutine definitions is confusing for everyone

using variables before they are defined doesn't work , Coping with Scoping

strict+warnings complains about using vars before they are defined

make more subs, make your program readable

make skimmable code :)

So you write

Problem with JsonRes? You delete/remove all the CGI/LWP stuff from the program and only deal with JsonRes

Problem with LWP? You delete/remove all the CGI/JsonRes stuff and deal only with LWP
