[SOLVED] Code does not run when assigned to a variable

I am more of a newbie, but wanted to post this in this forum as I was afraid no one would look at it in unix forums as it concerns shell scripting. I have a shell script that now runs fine with the exclusion of one line:

x=`su nbadmin -c "ssh -t servery /usr/openv/netbackup/bin/bplist -C servery -t 19 -l -R -s 11/01/2012 -e 11/01/2012 /vol/root/"`;echo "$x"This command will run and ssh to the server. It prints out /vol/root after it sshs to servery. However, it does not print out a list of the contents of /vol/root. However, if I run the command WITHOUT assigning it to a variable, like this:

su nbadmin -c "ssh -t servery /usr/openv/netbackup/bin/bplist -C servery -t 19 -l -R -s 11/01/2012 -e 11/01/2012 /vol/root/"It runs and prints all the directories under root. What is it about this command that you cannot assign it to a variable and it won't print out the contents? The bplist -l -R options are supposed to do that and they do so long as I do not assign the command to a variable and echo it.

Any help would be welcome from you gurus!

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
atf-sh(3) BSD
