sed substitution

Hi I am trying to do a text insertion in a text file at a particular line number in a shell script. However its not working.


Code:
sed '122i\
> for j in \`echo $MyList\` ; do perl -pi -e\'s#01\/01\/2009#01\/01\/2011#\' $j ; done' $HOME/MyScript.ksh


The Actual line to be inserted at line 122 is:

for j in `echo $My_List` ; do perl -pi -e's#01/01/2009#01/01/2011#' $j ; done

Why is it not doing so?
Please tell me how to do it.
