When I run the WLST script .sh script to set the env as follows why can't I see the updated path when I do echo?

[linbox2 bin]$ ./setWLSEnv.sh CLASSPATH=/directory/ols_wls/patch_wlss1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/directory/ols_wls/patch_wls1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/directory/ols_wls/patch_oepe1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/directory/ols_wls/patch_ocm1031/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/directory/ols_wls/jrockit_160_14_R27.6.5-32/lib/tools.jar:/directory/ols_wls/utils/config/10.3/config-launch.jar:/directory/ols_wls/wlserver_10.3/server/lib/weblogic_sp.jar:/directory/ols_wls/wlserver_10.3/server/lib/weblogic.jar:/directory/ols_wls/modules/features/weblogic.server.modules_10.3.2.0.jar:/directory/ols_wls/wlserver_10.3/server/lib/webservices.jar:/directory/ols_wls/modules/org.apache.ant_1.7.0/lib/ant-all.jar:/directory/ols_wls/modules/net.sf.antcontrib_1.0.0.0_1-0b2/lib/ant-contrib.jar:
