Question Read from file and execute the read command

Hi,

I am facing issues with the below:
I have a lookup file say lookup.lkp.This lookup.lkp file contains strings delimited by comma(,).

Now i want to read this command from file and execute it.
So my code below is :
Contents in the lookup.lkp file is :
Code:
c_e,m,a,`cd $BOX | ls cef_*|tail -1`,/home/me

In my shell script I read it as :
Code:
$(cat lookup.lkp | grep c_e | cut -d ',' -f4)

So above command should pick up
Code:
`cd $BOX | ls cef_*|tail -1`

which it does....but the command does not return the file name starting with cef_some_name even though there are files which match the wildcard.
Instead it quits using no such file or directory.

How can I execute this.Any help appreciated.
