Option strict on disallows implicit conversations from string to Boolean

Hey

if activity will look for boolean value, so if you have string variable you will need to add any kind of validation or function that returns a boolean value for example

out_str_inVeritification.Trim.ToUpper.Contains("anyword")

or also if you need to look for any element exist you can use the element exist activity or also the Check App State Activity

Regards!
