What's the hottest city?

Hi everyone,
I am doing this off-platform project and am stuck at step five. `#!/bin/bash

cities=(“Paris” “London” “Granada”)

temperatures.txt

for city in ${cities[0]}
do
sleep 1
echo $(./weather.sh -s $city)
done
`
This is what I wrote, it is (I think) exactly as in the provided solution but my terminal keeps displaying that the ‘-s’ option is illegal. Is there a problem with my code or is it the weather.sh that doesn’t provide the simplified option ?

Cheers,
Pierre
