@BAS-Viet-Nam Okay, thank you for the hint. Worked on many sites with these 2 functions without any problems. So I will try it with "Wait while element exists" on this specific site.
Hopefully I don't get in an endless waiting-loop ;)
@kmishu96 The first thing is u need to record the http request from hotmail signup page till finish, and use the http record/sniff result, its not easy bcoz microsoft/hotmail have much protection etc. or u sniff all request from another sniff program and put into BAS :)
I haven't tried but should work. You can create array by going to "create value in visual constructor " -> " create empty array " and also, other array operations are available.
