I found the problem. My single quotes within the sed lines were being stripped off causing eval to choke.

changing:

do echo -n '| sed -e 's/ `echo $i | cut -d" " -f2`/ `echo $i | cut -d" " -f1` `echo $i | cut -d" " -f2`/g' ' ;

to a double quoted:

do echo -n "| sed -e 's/ `echo $i | cut -d" " -f2`/ `echo $i | cut -d" " -f1` `echo $i | cut -d" " -f2`/g' " ;

fixed the issue.
