Ok, you need to "source" the script if you want all variables inside it within
your current shell. Try this (assuming your script is in current directory)

source ./

and try now. You'll see that all variables you defined within script are now
part of your session. Another shortcut , instead of typing source, try this:

. ./ (that's period space & then your script)

The probem you are having is that, when you run your script a new shell is
created (the one that is going to actually run your script) and then after
the script ends, that shell dies and control resumes back to your shell.
