> $result="$result $next"
Remove the first $ perhaps?
Like your other assignment earlier on.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.

The above from Salem's post needs to be done to fix your issue.. but you may also want to fix your if statement.
The data in these variables are strings and need to be compared as such.
It probably isn't necessary, but you may want to say:
if [ "$result" = "$next" ]
