I hope my wording is correct here.
I want to update a certain set of rows per iteration.
In my iteration I use different accounts that all have different passwords. We have a flow we want to go through were we want to change/update the password. I want to keep the tests as dynamic as possible so when the password is typed I want to extract that value and update the Spread sheet for the next time we log in with that user.
So to give more of an idea.
Iteration 1 uses User1 with Password 1.
He goes into the application and then selects to change his password to Password 2.
I then want to update the password only for User1 as our screens are rendered for the type of account you have.
