match='<color="red" \/>'

Or change the search/replace delimiter characters to something else

Code:
sed "s#$match#&$uservar#g"


By the way, the backslash before pattern flag g is not correct, it should be a forward slash /g and I do not see any reason for it to exist, in this case.

Thanks.
Idea behind all this is to read user input in numbers from 4-8, and each number present a different html tag and with more options.
So if user input is 6, it will added 4,5 and 6 after $match string.

But now for the test purposes i wanted to put maria if user input 1, but i cant, why?
Code:
case $uservar in
  1) echo "$text" | sed "s/$match/&MARIA/" ;;
  2) echo -e "\nYou are 2" ;;
  *) echo dont know ;;
esac

it returns me just my $text variable
