Bash sed command help

Looking for some one who is good with "sed" , I am making a bash script need to uncomment a line.
For some reason my command is not working, this is the command"
# sed -i '/readclients = yes/ s/^#//' /etc/raddb/sql.conf # with no hash marks
When I check to see if the hash was removed is still there.
Any one that wants who knows that wants to make a quick $5 ?
Need this work right now any one ?
