putting a path into a varaible and change directory

I have this script that just unzips a few files.
I have labeled this directory in the "basename"
name space. Which is great becuase I don't have to
write out the whole thing in the line every time I
reference the path. However the script does not change to the
directory. The "cd to $basename" does not work.
the script does not switch to the basename direcotry after it is done .

Code:

  #!/bin/bash

    wrapper_date=$(/bin/date +%Y%m%d)



    base_path="/sbcimp/dyn/data/EVT_RESEARCH1/engine_logs/qgen/"

    file1="/casper-process-1.log"

    file3="/casper-process-3.log"





    gunzip "$base_path$wrapper_date$file1.gz"

    gunzip "$base_path$wrapper_date$file3.gz"

    #does this not go to the next command unless the gzip is done.

    cd $basepath

    pwd

$basepath undefined.
cd $base_path

Could be a typo but the shell does not inherit a program's environment (actually it is a child process) even though you change directories from within the script once it exists your back where you started.

Or you can use pushd/popd to change directories and return to the stored directories when you're done.

Cheers
