If "error" happens?

[Potio]

Hi,

i am new to this bot and trying to learn of the script logics.

My usernames are saved in usernames.txt file and i've loaded them in "Resources" in BAS. How can i make it so that if the "The username is already used" error pop up appears, then BAS tries to use second line of usernames.txt?

Hello just clic in the email field and sleep 3 seconds, then catch the error by using :
IS ELEMENT EXIST and IF ISEXIST
