Execution of script.sed gives error in ubuntu?

I have a .sed script in which I have a code to make changes in a dataset. The code is as follows:

"s/,BEL,/,Belgium,/g" -e "s/,IT,/,Italy,/g" 

However when I run it as follows I get the following error:

sed -f script.sed dataset.csv

sed: file script.sed line 1: Unknown command: '"'

Any idea of what I may be doing wrong?

>Solution :

Replace

"s/,BEL,/,Belgium,/g" -e "s/,IT,/,Italy,/g"

with

s/,BEL,/,Belgium,/g
s/,IT,/,Italy,/g
