Sed text replacement issue.

Hi,
Im trying to find and replace text within a unix file using sed.
The command that i have been using is

sed '/,null,/ s//, ,/g' result.txt>result.tmp

for replacing ",null," with ", ,".
But this only replaces the first occurrance of ,null, in every line. I want to do it globally.
It works fine if i exclude all the commas.
Please help.
