arrays and while loops in bash

hi guys,
i have an array called ARRAY which has elements in it... i am trying to assign elements of ARRAY to master_array..
i get a =: command not found error..
Code:
i=0 
while [ $i -le 11 ]
do
${master_array[i]}=${ARRAY[i]}
((i++))
done

is there something i am missing?

This may work:

Code:
i=0 
while [ $i -le 11 ]
do
master_array[i]=${ARRAY[i]}
((i++))
done
