@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 ;)
Thank you! it worked, i was using [[VARIABLE]]/Images.txt with expression, it was also giving me error but then i used it with string then it worked. I thought in string, variables values cannot be used :)
