WHAT is not working - post the error msgs!

And, you don't need the command substitution in the for loop. And, you seem to terminate the second command substitution too early - the awk doesn't have input nor output files (actually, it works on stdin which is the pipe from echo $i).

awk doesn't need the for loop - it can work on a series of input files by itself.
