Edit script but it still run old script

[pouralise]

String, number - no difference. You still must use a object where your user will type the values and your script will just read this.

Let say when they want to send the email to 100 user, if I use object or storage to store that value, it's not a wise idea. My Idea is I can use only one object.
Example
The script I want to edit is 1/0/1
1/7/1 will store the email address

When 1/0/1 = 1, they want to send email to "abc", they will set 1/7/1 to "abc", 1/0/1 will be set to 'email("abc")'
then they want to send to another email "abcd"  , they will set 1/7/1 to "abcd" , 1/0/1 will be set to 'email("abc") email(abcd)'
